2001, model with 4-10's. Problem occurs with or without input jack. Neither volumes affect noise level. On standby, there's no noise. I replaced the tubes, inspected & cleaned the sockets, big resistors measured in spec, all solders appearing to be good around the pins. Any other specific suspects before I dig into it tomorrow?
One other odd thing I noticed was the bias voltage, schematic calls for 60mv but it measured 119mv, twice spec. Is that because it has 4 speakers or just that the last tech didn't adjust it properly?
