No luck for me finding any. What is the issue?

I know I have posted them here in the past.

All the SGs were pretty much the same as I recall. The 100 watt had a pair of 8417 while the 200 watt had four.

I have worked on the 4 tube model some 18 years ago and there's no hidden tricks in the amps circuit so you really should not need a schematic.

What's the issue with it, not working right or did someone mod it as was the case with mine I had to repair?
