This old Rotel RA-840B powered up but had no output.

Rotel RA-840B Repair

Compared to some amplifiers this faulty Rotel RA-840B amplifier is a fairly simple design as it doesn’t have any tone controls so it isn’t crammed with electronics and multiple circuit boards.

It was also easy to take apart which makes repairing it easier.

The no sound problem was due to a fault with the power supply.
