I picked up what was listed as "only for parts, not worth a restoration" sale on that auction site, along with the matching T-526 tuner. But, I wanted a challenge, so purchased it anyway. Here's photos of how the unit arrived (there'll be a separate thread for the tuner). Though I can't really dig into it right now, as I promised the spousal unit I'd finish off the bar I'm building and get the basement and garage straightened out, I couldn't help but at least put it on the dim bulb and do some basic checks. I only had a 2A slow blow fuse (unit states 3.5A) and 3 amp fast blows (vs 3.5A) for the speaker protection circuits, but voltages checked out, Bias was almost spot on at 8mV, and DC Offset was 8mV Left and 20mV Right. Haven't hooked up speakers yet, but I may do that test later tonight just to get a "before" sound impression.
So, here's another "Ugly Betty" restoration on its way. I'll be using parts on hand for the most part, but I'll most likely buy some new rack handles since they appear to be standard drawer pulls. Suggestions welcome as to how to deal with the corrosion and rust (wire brush, Naval Jelly?, just use cold galvanizing paint?...), transistor subs if needed (I may replace the differential pairs [2SC1000BLs] with BC550Cs since they're also low noise and have a high beta group like the originals. I'll also probably swap out resistors in the signal path for high quality Dale RN60Cs. But, I want to listen to it first to get some impressions about the last gasp of breath for HH Scott gear.
