I finally had some time to look yet again at my ailing Mc2300.
The main problem remaining is the overheating left channel transistors. However, there is also some detectable background 60Hz. hum in spite of the fact that all of the + - caps have been replaced except the 39000uF. can caps.
Anyway, I was playing around with the stereo/mono switch (Deox'd several times) and the amp is again running cool!
My question is: Does anyone know what is the type, and current handling spec. for that slider switch? That information does not appear in the service manual. I was going to pick up the correct 250K volume Pot for the amp today. (I installed a 500K pot that I had in my parts box) I thought it would be a good idea to replace that switch, since it is now a suspect in the heating issue.
Any information would be much appreciated!
