Hello, is there Cary 300 SEI user or tube AMP users experience bias adjust. About a week ago, I turned on the 300 SEI; the tubes light up and LED is on; but when I tried to play music. There is no sound. I used my
the other amp to doble check other components that work fine. What do
you think where the problem is?
Cary technician claimed I may experienced a voltage spike/drop in your AC line. They instruct me to reset and adjust the bias with DC-mA meter. But when I connected the meter to the AMP with bias adjust cable, I can't adjust the bias by the bias pot; and I don't think the meter can read the bias through the bias adjust cable, but the meter works properly.
Please Cary owners and tube AMP user help me. Thank you advance for all your comments and suggestion.
