Classical Music Format Collecting. They All Have Roundness to Them: LP CD TAPES

Gentle reader,

I belong to a number of FaceBook groups of people with whom I share interests. I used to belong to a number of LP record groups, but some of the members were.....I'll not say.
I did recently join one devoted to collecting LP vinyl records filled with Classical music. 

I'd previously written about the hobby but from the standpoint of learning about the composers and musicians (and orchestras) that created and/or recorded the music.

I am 62 and grew up in a home that often had music playing. Dad had a fairly good stereo based upon what he earned as a Presbyterian minister. He and Mom had varied taste, but Dad like classical which certainly influenced my interest in it.

I also like: Classic Rock, Pop, Comedy, Film and Television Scores (often referred to as "Soundtracks") Jazz, both Smooth and what I call Traditional, Big Band, Classical of course, and even a little Bluegrass. As long as they don't sing. I even have a couple Country CDs. I found both separately, both are autographed and both happen to be beautiful women. Pretty good music.
This is the Classical LP shelves. They are two, but connect to make one. An incredible thrift store find! It appears they were purpose built to house LP records. 
This was another, earlier, thrift store find and it too seems to have been (home) made to hold records. I will get around to finishing the wood that the builder did not get around to. It resides in the closet of the listening room.
It has all the Jazz LPs, Big Band as well as Pop such as Frank Sinatra and other singers. Also holds Herb Alpert and spin offs from him, Al Hirt too. I like trumpet music. 
Further down are miscellaneous such as International music, Spoken word, Comedy, Historical and Test LPs.
Here is where it all began. This is a cabinet I made from white walnut wood. The type of walnut trees that provide edible walnuts. Rather than black walnut. Inedible nuts, but gorgeous, dark wood. I was 19 at the time and I bought the wood from my girlfriend's father. He taught me how to construct panels from multiple pieces of wood and other techniques of joinery.
The top shelves hold Classic rock and Pop. Bottom shelves house the film and TV scores. Some of them, mostly my wife's are ones with music (not the score) that was featured in the movies. Usually rock or pop artist's works.
This oaken rack was a thrift store find. Must have been made from a kit. It houses 300 CDs. I wrote about my rebuilding and finishing it here:
This shelf and the small rack upon it holds box sets both within and without. Mostly Classical, including one or two which are SACD sets. The blue one on the left is the most expensive CD I have. The Score to Galaxy Quest. My wife spent $65 to get me that CD!
This rack holds 200 CDs and contains the rest of the SACD and HDCD collection. It also holds all my Herb Alpert CDs, Classic Rock, newer Rock and Pop, the two Country CDs and I don't recall what else.
This is a mishmash of three racks. Top holds 100 cassettes of various genres. Both mine and my wife's. In front of it are the three deluxe 2-CD sets of Scores from the three Hobbit films. The middle and right one look funny because they both had flash hot-spots. I eliminated the white spots by replacing it with the color of the boxes.
Beneath that is W to Z of Jazz, then traditional Jazz, Mix CDs of Smooth Jazz, Jazz used in films, Western film Score compilations and compilations of other film Scores.
Bottom is the latest addition and simply did not have any room to mount it vertically. Sigh. It has some modern versions of Big Band as well as original artist stuff both compilations and artist specific. To the right are from the last resurrection of Big Band and modernization thereof. Cherry Popin' Daddies and others. From the 1980's, if I recall. There was a briefer one in the 1970's when Big Band was set to a Disco beat. I have a couple of those on LP. Fun to listen to. One is on clear yellow vinyl.
The biggest for last. This 400 CD rack holds most of the Jazz and most of the film Scores collections. As you can see, I prefer CD storage that holds them horizontally. A PITA* to add new ones since each that will be alphabetically below the new ones must be removed and moved down one at a time.  

*Pain In The Ass.

Now, you may be thinking, "Cassettes are rectangular." Yes, but they have tiny round tape reels inside of them. I had reel-to-reel decks in the past, but never collected prerecorded tapes, and decided that they served me no real purpose.
With a CD recorder, middle shelf, on the left, I can copy or compile mix-CDs, record from LPs and even  cassettes, and listen to them in the car or elsewhere. The only portable cassette player I have is a Walkman-style one. I never use it. I do have new blank Chromium-Dioxide tapes if I do decide to make some tapes.

Now that I've shown you my entire music collections, let me get back to the subject at hand. Collecting Classical music

As you no doubt know, "Classical" is generic term for what is sometimes referred to as "Western music". Not to be confused with "Country and Western". Western as opposed to Eastern music, that which originates from Asian countries and composers. The time-frame starts many hundreds of years ago and continues to present day composers. Generally it refers to music made for instruments used in orchestras. Whether solo works for piano or violin, for instance, all the way to massive works which might have hundreds of musicians and a large chorus of singers.

I will not go into the different eras of Classical music those can be learned elsewhere. My preference is Orchestral, the bigger the better. Do I like chamber music? Sure, if I'm in the mood. I don't have a lot of it. Preferring later chamber music. Such as Copland's Appalachian Spring which was originally written for chamber orchestra. For example I agree that Mozart was brilliant. But I don't really care for most of his works. I think I have one LP of his music. Heresy? Nah. Just my preferences.

As far as Baroque, I have most of the more popular works in the collection. No self-respecting Classical music lover would not have some Baroque. But generally I feel that it is overplayed, at least on our local Classical station. And earlier than that, no thank you. Sure, some of it is moving music, just not my thing.

I did take the extremely long time to go through all my LP records, one at a time and enter them into Excel spreadsheet programs for all of the genres. I wrote about that in a three part series. The last is linked below. Previous chapters are linked in the article.

My oldest LP is from 1949, shown below. And it is of my favorite Opera. In fact the only opera which I own. I have several versions of Boris Godounov on LP and CD.
See, lower left corner, above: "copyright, 1949, columbia records, inc." I don't know why it's in lower case.
All my collections are all alphabetized, with the exception of the "Various Composers" Classical LPs which are by label. I also separated the Mono from the Stereo. I at one time tried to have a separate mono music system, then realized it was silly. 

My collection exceeds 3000 discs and I doubt that I will ever listen to them all. I even stopped buying music after completing the database. But eventually started buying again. You either have the collecting gene, or you do not.

You probably also know this: a Song must have Singing. If there is no singing, it is a Piece of music. Or a tune, if you prefer. Or even a Work. I know, I'm a bit anal.

Two of my all-time favorite Classical works are Tchaikovsky's 1812 Overture and Beethoven's Ninth Symphony. I have not counted them in a while, but I have a LOT of each of them. Both large, grandiose pieces, for sure. But that is what I told you earlier that I liked.

Final words. We moved to Richmond, Virginia from Denver, Colorado right after I graduated from high school in the 1970's. Every 4th of July, the Richmond Symphony performs at a place called Dogwood Dell. It has a natural amphitheater. Behind the bandstand is where they place the howitzer canons from Fort Lee. One cannot see them unless you are off to the side or way up at the top. I would climb to the top as the 1812 played and ease my way over to the left side. I wanted  to  watch the canons fire. Of course, the 1812 Overture in condensed form, is the last piece they played.
There are three sensations to explosions, in the order received by our brains: Sight, then Sound, then Concussion. Granted they are firing blanks, and probably low loads of powder since many people are nearby. But as a teen who played Army as a kid, seeing, hearing and feeling those canons fire, WOW it was awesome!

I want to thank you, once again for taking the time to read my humble blog. When I set out all those years ago, it was just something to do. Little did I dream that people, lots of people would actually read and enjoy my writing and photographs. But it is each readers choice to click on that link and start to read. You chose to do that, and I thank you. You, make it all worthwhile.

Replacing Analog 2.1 Amplifier with Digital TPA3116 Class D 2.1 Amplifier in a Gaming Chair and a Subwoofer!

October 2, 2018

Gentle reader,

For longtime readers (thank you for that!) you are aware of one of my hobbies which is sports car racing simulation. I do not have a gaming PC, they are beyond my budget for a good one. 
Plus, since I must have a steering wheel and pedals, an XBox One and the expensive wheel and pedals available for it which I would need are also out of my fixed income budget.

It all started years ago when a buddy game me some PC racing games including Test Drive Le Mans. The 24 Hours of Le Mans and it's offshoots (WEC, ALMS) are my favorite type of racing. With vintage racing of the same types of cars interesting me even more. 

I've been into cars 60 of my 62 years. I'm told that when I was 3 or 4 that I could identify any car I saw, year, make and model. We lived in rural Kansas then, so not likely any imports then and there. But I think Mom exaggerates. 

I wrote about this previously quite a few times, but I am linking only the ones that relate to this story below, oldest first:



This is an older photograph, much has changed, but it gives you the layout: My desk is in one of the bedrooms, and has been since we moved in 17 years ago. My back is to the wall facing the wall which has the shelf you see here. So the sim-rig is facing right from where I sit, on the other side of this desk. Not a lot of room to maneuver in here. 

My wife gets me, so she supports my hobbies. She bought me that gaming chair to race with. It has a built-in 2.1 channel amplifier with stereo speakers in the headrest and a "subwoofer" beneath the seat. It is made mainly for kids to teens, being 6' 3" I had to extend the leg area by fabricating brackets and building a cushion to go beneath my knees. Poor ergonomically as well as it promotes slouching, so I added a lumbar cushion as well. It rotates and rocks and has folding arm rests. I added cushioning to those too. But you can see all that in the earlier articles.
The X Rocker has a transmitter which you can attach your audio feed to and it transmits to the receiver/amp. But it eats batteries and I prefer to direct wire things. No Wi-Fi for this old guy.

The amp is cheaply made and soon the contacts inside the green input terminal stopped working, so I found that plugging into the output also worked. But then it got wonky and I had to wiggle the plug to get both channels working. Oh, and the power plug also stopped working, so I had to solder the wires directly to the circuit board! 
This is what you see when it is removed from the chair. Notice the holes have broken on some of the screw holes. Cheap!
Once the black cover is removed, the board is revealed. Single red wire is the antenna.
Aluminum piece is the heat sink, one transistor on each side. So it has that, at least. 
Here is the comparison of the old analog board and newTPA3116 Class D digital 2.1 amplifier boards, Tops above and bottoms below.

I chose a blank two-gang plate to make the new face from. Oh, that is the cover for two light switches that has no holes in it. Electrician term. I used a Dremel tool shape the white piece to the contour of the original so that it would fit smoothly into the hole in the chair. 
Locktite brand Super Glue Gel secures the plastic plate to the rest of the faceplate. I repeatedly heated a utility knife blade with a propane torch to cut out the recessed section of the faceplate. 
I glued small flat washers to the rear of the three holes that had not yet broken and larger ones to the front. Gel super glue is fabulous for things like this.
I discovered once I installed the knobs that if they are pressed fully on, they will not turn, at first I wondered why, then realized, it is genius: Once you set each to your desired level, press them in and they settings cannot change. Prevents little ones from messing with the knobs. My youngest grandson, and the four before him, loves to turn knobs. Many a time, I have forgotten to check the HT receiver's volume position after he visited, and when the sound starts, we both about jump out of our seats because it is SO loud!
No directions come with the amp, but the eBay auction page has this clear diagram as to what attaches where and polarity. What was not clear to me is which is + and - on the right speaker, blue or white? But since the drivers must be small, bass is negligible, so polarity for engine noise should not matter.


I enlarged the original volume control hole to allow the plug to fit through it. All hooked up, above and in place below. Flat washers do the trick to allow the new screws to firmly hold the amp to the chair.
I taped the diagram to one of my desk's speakers so that I can learn which is the main volume knob. I set the other two so it is the only one that can turn. I find myself trying to turn one of the input cable terminals sometimes, though!
I removed the larger driver I'd installed previously and drilled a hole in the center of the grille to allow these new wires through. Because........
I found this KLH 8" subwoofer at Salvation Army! I tested it in the store and had sound for a few seconds, so I knew the woofer worked, but suspected the amp. Price was right, as was the size.

I found the previous owner had first replaced the fuse with a 5 Amp one. When that didn't work, he bypassed it with a wire! Idiot. I soldered the woofer's leads to the (circled) input terminals on the inside and now it is a passive subwoofer. 

There was also no fiberglass inside. So I added a mat to the bottom and rear wall, which covered the amplifier. Sounds great, especially when racing with a car with a large V8 engine!
I have not bought a Class D amplifier before, or a Chinese electronic board, for that matter. But, it is well made, here are the specs as shown in the eBay auction:

"Features:
Adopts high quality TPA3116 digital amplifier chip.
Sound quality is very good, high efficiency and amplifying power.
50W*2+100W 2.1 channels(left/right channel and subwoofer channel), high efficiency and low-heat.
Powered by DC 12-26V, wide input voltage.
User can adjust the volume by themselves easily.
Applicable speaker impedance: 4-8 ohm.
Just connect the power supply and loudspeaker box, enjoy the pure digital music!

Specifications:
Supply Voltage: DC 12-26V
Recommended Power Supply: 24V DC >5A
Chip Type: TPA3116
Channel Type: Left Channel, Right Channel, Subwoofer
Output Power: 50W*2 + 100W*1 Subwoofer
Output Match: 4-8 ohm
Audio Output: Terminals
PCB Board Size: 105 * 77 * 28mm / 4.13 * 3 * 1.1in (L * W * H)
Weight: 138g / 4.86oz"

It sounds terrific, and with a real (as real as a KLH 8" can be) subwoofer, the audio is much more realistic. I do not play it too loud since these are the only ears I'm ever going to have and hope to still be using them unaided the rest of my days.
I redid the knee brace that I originally added to the chair. It was too low and I made do by placing a pad between it and my knees. 
I took it off and apart. I added the padding inside and then put it all back together, but it still was a little low. I added a one inch square tubing between it and the angle iron frame and that did the trick. A mesh curved lumbar pad eliminates the poor posture the chair design promoted.

So, there you have it. I really appreciate your taking the time to read my humble blog. I had no idea anyone would read it, but I have a large response to every article and get great feedback from my readers.

Thank you,

Scott
