got one at a meet, unfortunately, it is a variant to the 2 schematics that Steve Johnson has on his site, using 6sn7, 6ac7, 6sg7, 6sq7 and 80. Some one has monkeyed with it, but looks to be some cap changes/replacements, but loose wires make it somewhat hard to rebuild. I know that it is a variant, and not just someone slamming tubes in it, the resistor from pin 1 to 3 (2K) is missing, and a wire is in its place, that wire is definitely factory wired. Anyone with suggestions/schematics, I may have to rebuild back to the closest version I have a schematic to, that would make this a winter-time 2015 project! thanks

Supreme manufactured these for a few years. The main difference outwardly is the later versions had a four position meter select switch. The early runs had a three position switch. There were major circuit changes between the two versions but I don't know how many different circuit changes were made in the later series over the years. Check your switch to see if you have an early version or a later version.

thanks, Steve, I have the 4-position meter switch version. The closest schematic is the Beitman from your webpage, but there are differences, both in some of the circuitry and the tube line-up. At this point, unless I luck across the schematic or manual, I will have to rebuild to the Beitman schematic...

Randy,

If you are going to use that one go and download it again.
The one I had posted there was scanned years ago. I just replaced it with a higher resolution one.

thanks, Steve, got it! And thanks again for your excellent website!
