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?

There’s always the silver plated audiophile fuse holder from Acme Audio Beep! Beep! to consider. Not for the timid. 😬

Does anyone know what the bias is on the VTL 225 with kT90's?
