Default Hickok 440 Curve Tracer Repair Help
In article ,
says...

Have you replaced any and all electrolytic capacitors and verified that
the resistors are on spec?

Capacitors are bigger suspects than the semiconductors...




In older equipment it is always to suspect the electrolytic capacitors
first. For older tube equipment the 1/2 and 1 watt carbon resistors
often seem to go up in value and are the next thing after the capacitors
I check for equipment that is sort of working,but not up to
specifications.
