Fender Concert amp
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? |
