I am not sure what it equals but here is what it looks like. I needed a small amp for my office which could sit on a shelf and have a minimal amount of wires going to it. I had a seriously beat up and rusty SCA-35 with good transformers as a base to start with. It had sat for years, who knows where, so was pretty nasty inside. I gave the chassis a light sanding as well as the transformers. I painted the inside a graphite grey and the transformers with textured graphite automotive bumper paint. I am not a fan of the SCA-35 preamp section with the 7199’s and tone controls so opted for a pair of ST-35 boards which I stuffed with Takman resistors and Russian PIO caps. For the power supply I used a JJ section cap, Mills resistors and a Hammond choke. Instead of the SCA preamp board I shoehorned a PAS3 line stage board stuffed with Russian PIO’s, Solen caps , PRP and Arcol resistors. It’s pretty tight in there but everything fits. I wish there was enough room for a regulated filament supply board but the amp is surprisingly quiet even using AC on the 12AX7’s.
The amp sounds fantastic and has enough juice to drive any of the bookshelf speakers I own. I redid the RCA inputs on the back but left the speaker connectors original. It’s not a big deal but I may change them to something better. I need to add a power indicator light as the bulb was burnt out. In all of the PAS3’s I have built I always change it to a LED but I use DC on the heaters so it’s easy to hook up. When I get home tonight I will make up a small board with diodes, resistor and a LED and see how that works.
