Speaker pop on amp startup - 1 channel only

4est -

That is what I plan to do but I would like to figure it out - I want to know if it is something that would affect sound quality or if it is just the equivalent of a cosmetic issue.

I did check the bias and it measures OK as specified in the service manual. Also the left speaker terminal measures 0 volts DC ~2 seconds after exiting protection mode - the right one always measures 0.

It was checked out by Desco Service Company of Olympia, Washington and they said it was OK other than the popping.

How much DC does it take to damage a driver? Won't a high pass filter block DC?

I may take it in to United Radio in Syracuse NY and have them look at it. In the meantime I my friend at work is going to look at the schematic and see if he can identify any likely culprits.

I believe so. It does it when there is nothing connected to the inputs.
