Go here for the schematic: http://pg.photos.yahoo.com/ph/aliwag.../ph//my_photos

Eduard Orvisky's Audio Page can be found here: http://www.geocities.com/oviktor/aud9.html It looks like he removed the schematic though. I'll try to post it here.

Anyone know of a good place to purchase these FETs?

I belive it uses a 10-turn pot.

www.Digikey.com has more than 10,000 OPA2134s in stock right now.

From what you described there are only 3 things you need to recheck: Miswired (or short) Backwards capacitor or a bad opamp The easiest thing to do is verify the cap polarity, then throw in any compatible, cheap opamp and see if it works. If not, you'v already narrowed the problem down...

Thanks CETOOLE for the information. I purchased a quantity of 10 and received 12 Noble pots like the ones shown above!!!!

Here's a nice application of this circuit. http://www.pha.inecnet.cz/macura/buffer_en.html

You cannot place opamp power rail decoupling caps, MOSFET gate resistors, and other "distance sensitive" components using wire-wrap. There will be additional noise and/or oscillation if you do.

It's great as long as you don't try to build any high-speed circuits with it. Wire-wrap can be kind of noisy.

Thanks, guys.

I was looking for HP amp enclosures. I would like to have a good Hammond enclosure source. My main concern is: I am in the USA and they are in Europe. I ordered something from China once and it took more than a month to arrive!

http://www.elfa.se/en/ I just wanted to know if they are reliable and fast with the orders. I live in San Diego, Calif. (USA)

...or crd (current regulator diode).
