A-75 parts for sale
Front end boards, double sided. Those are tested boards. Trimpots are placed on the other side. If you mount the boards directly on rear panel and drill appropriate holes, you can adjust the amp, without opening it. It is better this way, as the temp doesn't change. USD $50 per board.

I also have regulated PS for front end, delivering +/- 50V DC. Those supplies are based on ML23.5 amp. Schematic: http://www.diyaudio.com/forums/showthread.php?s=&postid=53308#post53308

Hi Peter, i'm interested to all the necessary to build the a75, like unreg power supply and output stages
Here are custom built 750VA Plitron toroids. They feature double primaries (115V) and 4 sets of secondaries. Main secondaries deliver 40V DC after rectification and another set of secondaries is for front end PS regulators and deliver about 70V DC after rectification and after reg, you are getting required 50V DC. USD $100 per transformer.

I have one set of output devices in TO3 cases. 24 x IRF230 and 24 x IRFP9130. I had to take 9 mosfets out of this set to built my Aleph X, but have more of them in another A-75 amp and can remove them and add here. They were not used much. Since those is not currently avaulable parts, I accept offers.

Still have capacitors that can be used in building A-75, or other amps

O.K. Peter i'm searching for all teh parts for to build an a75 exept the heatsinks, so transfos, big filter caps, diode bridge, reg. power supply, front end, output mos. It is possible for you to send it all to Italy? And which way to pay? I'm absolutely newbie
I was sending packages to Europe, so it's not a problem. Shipping will vary depending on weight, but it's not that high. Payment would be best arranged by Paypal, otherwise as sort of transfer has to be used.
