Rotel RA-840BX3
Anyone know where I can get a service manual for a Rotel RA-840BX3? Still waiting for a response from Rotel... but in the mean time.... if anyone already has a copy.

I got it with one channel blown and I am trying to debug the problem.
It doesn't seem to be a problem with the output transistors as they are not hot.

Anyone familiar with this amp?
