Rotel Amplifier RA-9808X

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

No sound to remote speakers in dining & deck areas.

Incoming from WHAT? Ampifiers accept inputs via RCA connections and send amplified audio to the speakers via the + and - OUTPUT terminals.

I'm guessing your colored wires are from your speakers and that there is a piece of this puzzle we do not see - how the speakers on the deck and in the dining area are wired.

You say, "was working ok previously"... previous to WHAT? Something changed.

You can probably troubleshoot and resolve this yourself.

Set the amp to a medium output level.

If the wires are simply leading to either or both pairs of speakers you could select any two of them and connect them to one side of the amp. Only a pair going to the same speaker(s) will produce sound. Once you identify one pair, the other pair probably goes to the other speakers. Connect them to the other channel output.

The last piece would be to establish correct phasing between the speakers. Bass response will suffer if they're not IN-phase. Play something with substantial bass. Listen closely, then reverse the wires on one side only. Test again. If it IMPROVES you have it right. If it losses bass, put the wires back the way they were.

Hi, I have a Rotel 1050 receiver that I am trying

I think the best solution is to remove the jumpers from the Pre Out - Mon In connectors, insert a pair of RCA Y-adapters and plug one end back to the Mon In while the other ends feed the NAD (Page 15 of the manual available at Retrevo.com) . The Rotel's volume and other controls will still be in charge of the NAD.

The manual fails to mention looping the Pre Out back to the Mon In to enable the Rotel's amp to still participate in the program material.

I have a problem with my RA-9808X.

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.

Right speaker jack not working

Why would it die from being in storage? Oxide or corrosion on contacts, volume potentiometer, Tape Monitor or other switch contacts.

Try manipulating all controls and switches throughout their ranges many times and see what happens.

Check the heaphone jack. If it works so does the right amplifier. While you're at it, insert the headphone jack multiple times to cycle its contacts, too.

Rotel RA 9808X Amplifier

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.

I have an old surround sound reciver ROTEL RSX-1067 Mabee 20-30-40 years old : one day it just shuts down, just like that.

Several possibilities come to mind. First shorted connections to speaker wires. Faults in the power supply. Sometimes if the unit has not been working for a while the large capacitors in the power supply can dry up. An overload on a power transistors.
