Gentle reader,
Today is the second day of my stewardship of a very rare 1994 Dynaco PAT-6 preamplifier. I wrote about it yesterday and it can be seen here:
Very clean setup seen here in one of the Panor Dynaco vacuum tube components.
I chose classic rock and jazz CDs first and sat sampling some from each disc. I am VERY pleased with the sound. An odd thing is there is a slight echo that I have never noticed before. Like ambiance from the recording studio, perhaps? It does not bother me, but it does surprise me. I have noted it in the past in some recordings, but the PAT-6 really brings them out.
Once I finished painting the trim on the stairway that heads down from our split-foyer, I picked The Doobie Brothers Takin' it to the Streets LP to test the phono section. I switched from my restomoded Baby Advent II speakers to the large Klipsch KG-4 units and used the Dynaco QD-2 to include the A25XL speakers. I removed the grilles from them all and watched the woofers for any sign of rumble. If you are not aware of this phenomenon, sub-sonic frequencies can cause woofers to visibly vibrate even though there is no audible sound. This can be destructive to woofers if it goes unchecked. A25XL speakers are not in this shot as the are to each side of my listening chair.

I am pleased to report that there is no sign of rumble! That was the final qualifier as to whether I keep the PAT-6. I do! I contacted the seller, Rob, about the PAT-6 and linked him to the previous article. He told me he bought it new at a stereo store near MIT in 1994 along with an Adcom power amplifier. Nice to know that I am only the second owner of this wonderful and rare piece of Dynaco equipment.
Here are some links to sites about the history of Dynaco:

Unofficial Dynaco Home Page The last is home page to the middle one.
The middle one is more concise and is the one most Dynaco fans turn to for answers. Here is what he wrote about PANOR:
"In the early 1990s, the Dynaco brand was picked up by Pan Orient
Corporation (now Panor Corporation), which started selling original
design equipment under the Dynaco brand; they offered the PAS-3 series II,
PAS-4, CD player, and Stereo 80 tube power amp. Panor still owns the Dynaco
brand name, but any direct connection with the company founded by David Hafler
has apparently ended for good. On the other hand, I have recently received
information from Panor, indicating that they have re-opened their web site at
www.dynaco.com, and that the Singapore web site is in no way affiliated with the
company known as Panor Corporation or with the Dynaco brand. Apparently the
Dynaco brand will still be around for some time, and hopefully still be
associated with high-quality low-cost stereo equipment (more products are
promised in the near future). I haven't had time to check out any of the
new Panor equipment yet, though. More news here as it is available."
I have spent some time going through my 2002 edition of ORION BLUE BOOK AUDIO and culled the following information:
Panor-Era Dynaco Components
Panor-Era Dynaco Components
Notes: Blk = Black Chassis. Chr = Chrome Chassis. Panor continued the Dynaco tradition of naming power amps by adding the per-channel output. Thus a ST-200 is 100 watts-per-channel output. Also note that blogger.com does not offer tabbing while blogging. So, if my ever-so-neat-in-Word-Perfect columns appear crooked vertically, that is why.

*These denote components for which I could find NO photos whatsoever. Many of the speakers also do not have photos that I could locate. Below are photos of which I could find. Most are from items for sale on the Internet in the USA or Canada. Most or all have probably sold.
NOTE: If any of these photos were made by you, please contact me so that I may add credit for them to this article.
First up is the CDV-1 Tube CD Player.
Note a lot of space inside. See CDV-2 to compare.
Next is the CDV-2 Tube CD Player.
Completely different electronics from the CDV-1.
Finally, photos of the CDV-PRO.
The addition of HDCD decoding is the only change seen in these three photos that I could find.
Below is an interior shot of the CDV-PRO provided to me by reader Jeff Noonan. Thanks, Jeff!
Next up are the MVP-100 and MVP-160 compact Tube preamplifier and power amplifier.
Aren't they dandy? I'd love a pair of these!
There is NO doubt that the Panor-Dynaco engineers were very busy in designing and building so many components. I think the prices, especially for the tube pieces limited sales. That and perhaps the snobbish view by some folks of these being interlopers trying to sponge off a vaunted name in the world of high fidelity and stereo. But I do not agree.
An aside: Here are photos of the very first piece of Panor Dynaco equipment that I found in a thrift store. I later found an identical, but black, PROTON model with a different number while researching whether PROTON and Panor were connected somehow.
Completely unlike any other Dynaco equipment. EVER.
All that is shiny is not golden, aside, back to the basic-black Panor Dynaco equipment. Starting with an add someone had posted with their PAS-4 preamplifier for sale on eBay.
Next is the PAS-3 Series II Tube preamplifier.
I suspect these were popular units based upon so many photos.
Super-neat circuit boards!
Continuing with the PAS line, I present the PAS-4.Next, although you may have already seen it are my new PAT-6 preamplifier-tuner.
Below, LOTS of empty space inside, but they are far from alone as far as that goes. Many a components I have opened up is that way. They were trying to make all their components have the same footprint and faceplates.
Next, we have the only Integrated amplifier Panor-Dynaco made, the SCA-120.
These photos are from an eBay auction. I watched but did not bid.
Disappointing use of cheap speaker terminals.
Back to Tube equipment with the ST-80 power amplifier.
Photos are from two different sources.
Next up numerically is the ST-100 Transistor power amplifier, the lesser-powered brother of my ST-200.
Visually identical to the ST-200. These too are from an eBay auction. This amp looks brand new and included the manual.
Built the same month as my PAT-6, here is the specifications sheet for it and the ST-200. The 200 weighs more and uses twice as much energy. Note: "PROTON ELECTRONIC....." on the sticker. Removing any doubt that PROTON made the Panor components.
And with that segue let me show you the only photos I had on hand of my ST-200. They are from:
A "Modern" Dynaco Amp, Onkyo cassette and Amplifiers I have known
That article, like this one is very long as it shows EVERY amplifier I have owned in forty+ years for which I have photographs. I compared the ST-200 to the Kenwood KM-X1000 power amplifier that I had been using.
Above is my first PROTON component a D540 integrated amplifier that I was using as a preamplifier. The ST-200 runs warm on the left channel, so a whisper fan keeps it cool.
Dynaco is quite a bit larger than the Kenwood.
Interior shots show the toroidal transformer and clean layout typical of Panor-Dynaco equipment.
I am enjoying a SACD via the PAT-6 and ST-200 as I write this.
Next and final for this first part of the two-part article are the photos which I could find of the ST-400 Series II transistor power amplifier at this time. This is odd as I have seen several over the years on eBay.
Sadly, no interior shots. As you can see, significant external heatsinks on each side of the chassis. Based upon where the speaker and RCA input terminal are located, I suspect it is a Dual-Mono design.
The only amp like that which I have owned were on a 150 WPC Mitsubishi power amplifier part of the vaunted DA Series:
The only other dual-mono power amp I have owned was this one-of-a-kind 1970's ST-120 of which some skilled individual combined two sets of power transformers, capacitors and associated components to make a very heavy and crowded ST-120 Dual-Mono amplifier:
Next time, in Part TWO, I will showcase photos of the QD series from Panor-Dynaco as well as all the photographs that I can find of speakers that they produced.
Thanks for looking,
Scott

Hi Bob! If interested, here's another representative from Panor. If you look at the ST-200 board, then here it is SCA-200 https://five.vn/tp-ho-chi-minh/amply-dynaco-sca-200-702194.html
ReplyDeleteWow! Thanks. I'd love to see photos of the rear.

ReplyDeleteWhile servicing a PAT-6 I noticed "PROTON" written on the circuit board. It's on the bottom of the preamp board. Love the interior pics of everthing.
ReplyDeleteThank you for reading my blog! Yes, the factory which made PROTON audio gear also built the Panor Dynaco equipment. In fact, I found a gold colored Dynaco five-channel integrated amp with a 4-digit model number. In researching that, I found and identical PROTON model, same number, which was all black. Also, the stickers on my Panor equipment have "PROTON ELECTRONIC INDUSTRIAL COMPANY, LTD." on the bottom of the sticker.
