Vintage Gibson GA-20T Combo Tube guitar amplifier repair Tremolo Tips

A cool relic comes to the shop. The T-20 was in pretty poor condition, but now has a voice again. During initial inspection, I was bewildered, Where are all of the eyelet board caps? Turns out Gibson decided to install them on the backside of the eyelet board! May have been an OK idea back then, but not now when you need to service the old gal. I decided the best plan was to relocate all components on the front side to allow for ease of future maintenance. There was plenty of room. Now the circuit can be traced out per the schematic. No hidden components.
