So...I started cleaning the x2 & x4 selector pot in the back (S004), and the other pots & push button switches...cleaned up any extra cleaner and let it all dry out. Hooked it all back up, fired it up and waited...No issues...or so I thought. I started turning it up little by little. Then I heard a screeching sound-I killed power immediately-relay did not. I blew some air in around everything and waited a day...thought there might be some excess cleaner I missed. Next day I powered it all back up. Now I have a hum through all channels, even if I have volume down-hum does not get louder with volume getting turned up-just constant. Selection of input has no effect on the hum. As soon as speaker selection is pushed in, the hum is there. So it seems now I am worse off then when I started...I checked off sets on amps, main power board and checked to see if I could see if any connections were loose, cracked or "hanging" on. Nothing, all readings are good...Slightly frustrated and about to use it for a door stop...
