Knew what? You said he doesn't use input transformers in his new amps but most of his designs including the newest 300 series do. The three models you called out are the only ones in production that don't and might be phased out in the near future.
Edit: jams just to fast for me!

jam said:Their latest model 302 uses input transformers. The model 12 has been in production for a while and will probably phased out in the near future.
And I notice that they're still sticking to the non-standard pin 3 positive on their balanced inputs.
Oh, and thank you arthur for the photos!

"I'm sorry Mr. Garrison.......
What I really meant to say was........."
I though new meant current, not something 5 years old that I really don't think is made any longer. Doesn't mean there aren't old ones left around that they would sell if you asked for one. I assume they are in business to make money.
Dirty secret of the audio business.......sometimes a manufacturer builds a product or series of products just to placate a certain dealer/importer/whatever. And then they have to live with the stigma of it a long time. Not saying that this is the case here, but I seriously doubt if you will ever see a JR product without a transformer again.

Pin 3 hot is standard everywhere I know of apart from the USA

If it is, then they're completely out of step with the rest of the world.
The IEC, ANSI, SMPTE, AES, etc. have all adopted the pin 2 positive standard.

I'm not aware of any standards organization or committee which has adopted pin 3 positive. Which standard are you speaking of exactly?

XLR standards
That is not so. Until the '80s you could still find XLR pin 3 hot on some European stuff, as you could find male chassis XLRs as mic inputs. You could still find microphones with Tuchel outputs, which were particularly hateful to deal with.
Fortunately those practices were standardized into using pin 2 hot, XLR female inputs and toss Tuchel style connectors away.
If we have to consider some standard, then microphones should be them and they are all pin 2 hot.
Only some dying hard pros will still go for some specific models from Schoeps that you can special order pin 3 hot.
Let's hope this info helps.

Re: XLR standards
Yes, and that's precisely what the IEC established as an INTERNATIONAL standard back in 1975 (see IEC 286-12). That's nearly 30 years ago! Various other standards organizations and committees have followed suit and adopting the pin 2 standard.
Anyone still using pin 3 as hot either doesn't care that there are in fact actual standards in place (as opposed to willy nilly customs on the part of manufacturers) or they haven't a clue that such standards actually exist.

Re: pin 3 question
Sure, but if you connect it to a preamp which has pin 2 positive, then polarity will be reversed at the amp's output.

arthur said:i think pin 3 or pin 2 is not a real question in jrdg amps
the actual o/p phrase fallows the i/p phrase
