Hello all,
This is my first post in this forum athough ive been reading around. This forum has some really great information on it!
Recently a friend brought me his Palomar 450 HD 4 transistor amplifier to see if i could help him out with an over heating problem. The amplifier uses 4 x 1446 transistors and for some reason even if the amplifier is in the "OFF" position the transistors start to heat up. The heating starts with one transistor (middle left) then the others start to heat up as well. They get to the point were they are too hot to touch.
I checked for a stuck relay but that part is fine. Anyone any idea what the heck is wrong with this thing?
Any advice will be greatly appreciated.
Thank you!
