This one came in for a set of valves and a check over. New JJs in the output and Tung Sols for the preamp, bias all OK and working fine except for random crackles.
PCB style amps are a pain when they start this, can be tracking on the boards from dust and/or moisture, dry joints or components that are noisy. An almost impossible fix.
Resoldered a fair bit of the pcb that holds the valves and it quietened down dramatically, but only time will tell if it does the job..........................
