AC Hard Start Kits – Everything You Need to Know
An AC hard start kit works by using a start capacitor to give the AC''s compressor an extra jolt of energy to start up. After the compressor starts up, a relay removes the start capacitor from the circuit to prevent the capacitor and compressor motor from burning out. The hard start kit wires into the compressor''s start winding.

Do you use your Standby switch? : r/GuitarAmps
Standby switches were not recommended for small receiving tubes, which guitar amps use. They were not common on guitar amps until the much-copied Fender Bassman. The reason why the Bassman had a standby switch is not known definitively, but it was probably to protect the filter capacitors, which were not properly rated for the voltage on cold ...
