Rotel amplifier RA-9808X components - Rotel Audio Players & Recorders

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!

check power amplifier component one should leak or damage so your power consumption is too high

It seems you have a short circuit in your unit. Further attempts at switching it on are not advisable as more damage will occur. Get it checked out by an electrician who can test from the plug for a short circuit.

All I can say to you is look around where the mains goes in very carefully. Fuses are sometimes hidden or in a case or cover of some kind. Sometimes amps use fuseable resistors. If the PC board is marked up look for resistors with "RF" or different indication to a normal resistor. Otherwise fuses will have "f" markings on the board. Remember the power supply part might be enclosed in a metal case with holes in it, so might be hard to spot fuses.

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

Instead of replacing you can try and clean it. There are a lot of good contact cleaners out there.

I'd suspect that one of the two output transistors on that channel has gone bad. If you are unsure how to test or troubleshoot this, then you might try replace both the NPN and PNP outputs and catch the bad one that way. If your amp uses an output module then you would of course have to replace the module which would replace all the output transistors on both channels. Good luck. Another thing to look out for, is the emitter bias resistors. They are the large white ceramic ones near the outputs. Sometimes one of those will open up too. They will be of a very small resistance value like .5 ohms (point five ohms) or something in that general ballpark, and have a wattage value of typicaly 5 watts. So they are pretty big resistors. Be sure to check them all even if you do find a bad output transistor. They will often go out with the transistor. Good luck.
