oscillation in power supply filter caps
Hello, I have two VTL 225 mono blocks that I just got and I feel an oscillation in the both of the filter capacitors on one of the amps only. They were made for VTL and have a value of 3800uF and 400 vdc. Could the caps have gone bad, I have ordered replacements for both, 4900uF at 400 vdc as the units I'm sure are 30 years old. Any thoughts?
