Hello all,
I traded an Bel Canto integrated amp for this ST70 Project with a member here a few years back. I managed to get most of the hard work done in the first couple weeks, and then there it sat for the past three years as you see it, when work and life got a bit crazy.
Has custom wound transformers for ST70, and the Triode Electronics Input and power supply boards fully populated. Base is a beautiful Mahogany.
The boards need to be wired up, Bias circuit needs to be added (for pairs or individual tubes), and Choke (Triad C-24X) needs to be installed inside base (not the exact C-354 choke, but should be close). Includes all you see - but no tubes....
I have all the schematics, wiring diagrams and directions. Should include all info needed to complete the build...
Just need to offload some projects I will likely never get to - including refurbing Apogee Scintillas, two pairs of Acoustats, Hammond AO tube amp Monoblocks, etc).
How's $650 + ship? Or pick up is west sub of Chicago?

Great-looking project amplifier for a good price. Wish I needed it. Someone will get a good deal. Good luck with your sale.
Out of curiosity, what power transformer is that? What specs? Looks big for an ST70.

Hello Francois,
I really don't know the winder of the trannies - the Power transformer is "oversized" tho... really wanted to finish but too much stuff in the way...
The tape is there to keep from being scratched up...
BTW - I was the DIYAudio member who bought the non working ARC D-76 and SP-3A from you a few years ago...I get down to Champaign every now and then for Football and Basketball games (U of I BSME Class of '87)

Hi John,
Yes, I ‘m the guy. I wondered what happened to the ARC D-76 and SP-3A. Did you get them operational again?

Hello Francois,
The preamp needed a new set of four diodes on power supply and a pot cleaning... the amp, I can not remember. The D-76 has this hidden diode deep between the cap bank that often goes out when power supply does not behave... an overly complex design (as most of ARC amps are), but this is common issue with them...
Both are now with a friend when he "just had to have it" after hearing them.

it's crazy that it is not sold at this price!
There are really things I don't understand in this world...
