Dear Dana, I`m also owner of ART D/IO excellent DAC ( highly modified ). But I wish to use JT-11P-1 line input transformer on the input of my Pass Aleph 0S amp...

If I understand correctly, you could use the JT-11P-1 to turn the unbalanced input of the Pass Aleph into a balanced input. The yellow wire on the transformer...
A friend of mine is an electrical engineer. When I told him I was thinking of driving a transformer directly from the DAC chip (without an Op Amp), he...
It's been a couple/few years since I've modded my DI/O, or even looked at the schematics, so bear that in mind with what I say... I think people who like the...
I too am an electrical engineer. Your friend is basically correct. In general, driving the DAC's with a transformer is a really bad idea. However, in this...
I built both and op-amp driven DI/O and a transformer driven DI/O (using Edcor's). I called the transformer output my "FrankenDI/O" partly because of its size...
More fuel to the transformer versus op-amp fire: I was about to try the "transformers" several years ago until I came across Gary Bronner's post about his...
Well, I too am an EE, and I know better than to ask any EE about anything audio...unless of course that's their hobby or biz. What doesn't or does work well on...
Ray, I don't think there's any fire. If you like tubes, and find SS (and digital for that matter) fatiguing, you'll like the trans output. It's a sound style,...
... Craig, I'd be interested in the mechanics of what you're talking about here - I currently listen using internal clock at x2 - sounds good to me! R. -- ...
Exactly. But you (we!) are in the minority, because it's not technically "right", synching to the source clock should be much better than synching to the DI/O...
No, floating, and no. I recall one person used the center taps to step up/down the trans input/output, to see which arrangement of the 4 possibilities worked ...
Chris: They are very clearly labeled, so all I need to know was the floating issue. I will give em a try tonight and then build my box with a switch to go...
That box thing...I might try that. Can't do it right now with the trans as they're in the stand-alone digital board setup, so would have to build a new box...
I found that a regular blue plastic wall outlet box, with a typical cover plate fit the Edcor's very nicely. I wrapped some metal tape around them and used a...
Well, it is only $17.30 US for a couple of new transformers, so you could get them that way. Yes, I did realize that I want a 4 gang 2 throw switch and to...
I think I'll add a big tube or two with filaments lit, perhaps a Tesla coil or Jacob's Ladder, a couple of knife switches, some porcelain insulators, glue some...
Well, that's the problem re the cost. Edcor charged me an incredible price to ship the 6 trans I ordered, at least double the value of the trans, then I got...
Riiiiight. Add a Van De Graff generator, fly a kite with a metal key on it, then strap yourself down. "They called me *mad* at the university." heh heh Jim ...
Damn, a crank-DAC. Brilliant idea! With the VDGG I'm off the grid, no more of that pesky AC. The kite-n-key-DAC might interfere with my zero-power-zero-bit-DAC...
I found my data sheets and must make a correction. The digital board voltages I said are OK, but not the current. What I measured on the bench was quiescent...
My general rule of thumb is to freeze and finalize dates about a week in advance, at minimum. Beyond this point, most of the details about the location will...
Thanks, good idea, people send me an e-mail. Re the rampage: I'll put all the valuables, priceless art onjects and the good furniture in storage...oh wait, I...
... Without any inputs, the CS8427 does not seem to get warm. I will continue to fiddle with this....but help is really appreciated - this should be simple....
Bear in mind it's been a long time since I've done this... I presume the digital boards are still working, as tested in the DI/O? Like, they'll sync on a...
