Bad splitter-driver plate/anode 100K resistor, what goes bad with them?
Causing rustle noise in output. Partial crack? or something chemical. I may
as well replace the 82K while I'm at it , but is there any point to
pre-emptively replacing all the HV droppers ?
Anyone happen to know the datecode structure for Mallory electrolytics of
the 1980s?
say 4uF, 450VDC
marked
012022
235
8346B

1982 and 35/52 from 235 or 1983 and 46/52 from the last number?



Noisy 100k resistors is a common and well known problem with Fender
amps, change em all.
