Re: Hacker GP42 and AL42 restoration help
Whenever I service these amplifiers, I replace the following on sight before powering up:
The two 220K anode load resistors on the top tag strip.
The two 820K and 1M resistor around the valve holders.
The two 2K2 and 220R resistors on the bottom tag strip.
The for 47uF capacitors on the bottom tag strip
The two mustard capacitors are almost always OK.
