Classic gear from yesteryear; vintage audio standing the test of time.

RE: Fisher Amplifier Voltages Questions

Hi Dave,
Don't ask me how I know this :-). Too many hours troubleshooting stuff only to find bad grounds. Now it is the first thing I do when I rebuild something. Check the key ground points. If it doesn't take my good meter to 0 ohms and stay there then I pop the rivet, install an internal tooth lock washer between the ground terminal and the chassis for a good bite, and then put a good old fashioned screw and nut in there. That is the way the darn gear should have been built at the factory. Rivets are nonsense in my opinion. Gear should be made to be fixed someday..... A good tube amp should outlive the builder or restorer.
