I just got a RM22 and when I turn it on it makes this noise. Video below. After a few seconds the amp operates without that noise. I have switched all preamp and power tubes and modules, and the noise remains. Can anyone help where to look? Bad cap perhaps? Grounding problem?
I appreciate any help.
