    Re: Rotel rack component wiring

    This is a complete rotel rack system. Amp RB-2000, EQ RE-2000, tuner RT-2100 and cassette deck RD-2200. Turntable RP-9400. Preamp of cource. Four BIC TPR 200 speakers. Father bought it new in 1984. Before noticing the problem with the preamp I figured out how to wire it up correctly I think lol . Went preamp out to EQ in then EQ out to amp in.

Spent one week removing face plates and all cleaning it. I will try and get some pics up. I appreciate all your help! I will get the preamp back together and functioning.

          Received my lovely new Nichicon caps

          Received all caps for preamp today. Only problem I see is the very small size of (10) 4.7uf 25v MW series caps. Several of them are for the filter amp circuit. They are 4mm x 5mm. The existing caps are 12mm x 20mm. I realized when placing the order that they were smaller just didn't realize the new ones would be so tiny. Question is will they be ok? Thanks

            Cap technology has changed in 40 years when these Rotel's were made, so I am not surprised that the dimensions are much smaller.

              do not ram them in, bend the legs carefully at 90' angles.

              if you just ram them in it puts stress on the rubber bung and they fail pretty fast.
              i have to fix this alot on stuff peviously re-capped.

                  Re: Rotel rack component wiring

                  Yee ha! Just finished up a 60 electrolytic recap on preamp. I also replaced 3 transistors on mc /EQ amp board. Retouched a bunch of solder joints. Just plugged in preamp and it powered up so then connected it to amp and the source was rush from my phone. IT WORKS!! Right channel not fading out anymore. This was my first attempt at anything this major. I soldered back about 20 wires that had been twisted around the post. I had every board out of this amp. Thanks for all the help!

                    Rotel RA-810 Fader Caps
                    by bermo96
                    Hi,

                    I rescued an old Rotel RA-810, after a little cleaning and new thermal grease for the transistor it works like it should.
                    But unfortunately the fader caps are gone, they are nice aluminum caps, so I want to try to find something similar.

                    Does anyone know if this amp shared these fader caps with other brands? Or if there is something similar on the internet?

                    The picture is for the balance cap, the faders have the black line running through the cap.

                    I'm looking for the wiring diagram for led monitor model DHI-LM19-L200
                    by gabri2211
                    hello everyone, I'm looking for the wiring diagram of this led monitor.
                    the model is DHI-LM19-L200, but I think that any other diagram of a DAHUA monitor could be equivalent.
                    I really hope that among you someone can help me to repair this monitor, the screen is black, it doesn't seem like a backlight problem.
                    I see the presence of 12 volts, 5 volts, but without a diagram the repair is very difficult.
                    thanks to those who will answer

                    Rotel RSX-1056 amplifier. Troubleshoot a noisy channel
                    by Francesc V.
                    Hi:

                    I've realized that one of the channels of this amplifier has no proper sound.


                    This is the signal at the speakers output.

                    As long as the audio coming in to the amplifier board (blue) looks ok although with some noise due to the wire, I think that there's nothing to look at the preamp section.




                    Now, I could start looking at components to see whether I find the guilty one.......but I would rather prefer to ask for advice. Here there is the amp. schema. Which points would you check with the oscilloscope to gather...
