Pioneer SA-1290 amplifier mutes, and does not easily un-mute. Has been getting worse, and I couldn't get it to un-mute at all. I would like to bypass the mute feature, but got lost in the schematic trying to figure out how. (I really appreciate having the manual available, that helped me a lot, and it is a wonderful service to the planet and your fellow human.)
If you could, please explain what connections I could short out, and any that should be removed to make the mute not work.
I understand if it is not worth the trouble.
