In Reply to: Should I re-bias Cary SLI-80 when replacing rectifier tubes and/or posted by Terry P on July 24, 2015 at 14:49:57:
Check the bias when you change either the power tubes or the rectifier tubes. A new rectifier may make the high voltage change (higher) especially if you originally biased with weak rectifiers.
Unplugging everything including speakers is not necessary. Make sure there is no signal entering the amp by turning the volume down. Unplugging the speakers is recommended to prevent a loud pop when you plug or unplug the bias test cable. Otherwise it doesn't matter.
