Für die Gitarristen unter uns, die einen Verstärker suchen und nicht 0815 wollen, kann ich [PLC-Vintageamp](https://www.pcl-vintageamp.de) empfehlen. Werden liebevoll schon seit zich Jahren in Deutschland hergestellt. Eigene Entwicklung. Sind Transistor Verstärker. Habe selbst vor Jahre einen custom design bauen lassen und vollkommen zufrieden. Für alle Stile geeignet, je nach verbautem Lautsprecher.

Preparing to install a new reverb transformer in a 1960s Gibson GA-20, I broke the terminal in question off of the tube socket. And subsequently realized I forgot to reorder 9-pin tube sockets. This thing has been on my bench for way too long.

On the bench: Gallien-Krueger 800RB
Problem: Intermittent input
Diagnosis: Cracked solder joints
Fix: Reflow that solder!

I completely rebuilt the filter section of the GA-20, taking advantage of the space I bought from cleaning up the power supply. The previous owner put the two filter caps they replaced on above three wire-wound resistors. Heat rises, and it’s important to keep heat away from capacitors as much as possible. These three resistors dissipate a lot of heat.

Replaced the power cord on the GA-20 with a grounded cable, removed the death cap, and rewired the rotary power/polarity switch to just power. I landed a 2 lug terminal strip on one of the power transformer bolts to provide a ground point and a more reliable connection for the pilot light and other half of the primary. The previous lug was badly corroded and broke off when I heated it up. Before and after photos below.

Currently on the bench: Gibson Minuteman GA-20 RVT. In for out-of-control squealing (oscillation) and a recap.

60s Gibson amps are a spaghetti nightmare, and the eyelet boards have deep, conical reservoirs filled with solder. The leads of every component are very long and are tough to remove, even with a solder pump. In addition to the oscillation, the reverb and tremolo aren’t working.

I have my work cut out for me.
