Ok guys, Ive seem to have hit a common problem with several of the receivers I am trying to get going again and for whatever reason ALL 3 have the same issue. The models are Marantz 2240, 2252b and a 2265b .
The problem they have is that one channel is distorted when in stereo mode and the other channel there is no sound. When i click the mono button i get sound out of both speakers but the one channel is still very distorted while the other is nice and clear.
I should mention that the 2265b was blowing fuses when i first got it so i replaced all the out put transistors and that stopped the fuses from blowing but now have this issues. I should also mention that i replaced the out put transistors in the other 2 as well just to see if that was the problem and that didn't do anything. I also have rebuilt the power board on the 2240 with all new capacitors. I have also cleaned all the pots on each of these units.
Does it seem strange that all 3 of these receivers have the same ailment?
With that said I turn it over to you guys for some advice on what to target on these to get them working properly.
