Removed the “death cap” and the high-voltage circuit in the speaker cable
Installed a new grounded power cord (and a proper fuse—someone had “jumpered” it before)
Light exterior cosmetic cleaning
Cleaned all pots
Tubes tested, verified, burned in; bias set; cold solder joints inspected; grounding improved, etc.
Notes:

Tube emission above 80%
