One side works fine but when I plug the speaker cord to the speaker out on the other side it fries  R87,R88.
I originally replaced R87,R88,R89, D36 and TR27 all with the correct values.( they were toast)
The TR27's outer casing was broke so I am not sure if it was bad but I replaced it none-the-less
Something made them blow originally but I can't see anything else that looks bad.
I do not have a scope....and short of testing everything....is there any tell tale sign that points to something that I should focus on?
