Where can Ibuy 2 capacitors for my rotel RA-840b?

Connect your Denon outputs to the Realistic main inputs.
Connect your Realistic main out to the Rotel tuner in.

Connect your Technics out puts to the Realistic Tape 1 inputs.
Connect your tape 1 out puts to your Rotel cd inputs.

And you should be good to go.

Try interchanging the speakers. If the right channel works, you have a problem with your speaker.

Hi,
I think RA 12 is not existing type, but RA 12xx types exist.
Please try this link, and I hope you will find the relevant documentation.
Good luck!

Hi George

If your powered subwoofer could accept speaker level input, like, say a Klipsch KSW-series, you wouldn't need it.

I don't believe that Rotel service manuals are available outside of authorized service centers. Can you provide us with the problem that you have? Perhaps we can guide you through the repair.

Thanks,
Dan

Hi Nell. It is serious. Unless you are technically inclined, it needs to be checked out by qualified person. It will be fairly expensive to repair. Get an estimate.
Thanks

Since it is a Rotel, it is a good unit and worth fixing. At this point, you need to take it to a good repair shop and let a qualified tech look at it. There are no user serviceable parts inside and if you go poking around in there, you WILL make the problem worse. Rotels' are nice units and represent a good value in stereo gear. Take it to a reputable repair shop that repairs Rotel under warranty. If thats not available to you, then a good repair shop should be able to get you going. Good luck...Rob

put 20a fuse in.

You may have blown a fuse on the left channel due to speaker wires shorting or a defective speaker. If there are no fuses on the rear of the amp there are probably internal fuses. They are usually glass with a small wire running from end to end. If the fuse is blown the wire will be broken. Replace with the same value of fuse.
