I have posted in Bartertown looking for a Rotel RA-1312 several times. I am Happy to report I received one today along with a Rotel RT-1024 Tuner as a bonus! The RA-1312 badly needs a cleaning but does work. I adjusted the bias and it plays well but lacks the "magic" that my Rotel 1412 has...

All 3 inputs used to operate around the same volume. Loud! Then, the phono started playing quieter, even when the volume is at 10. Now, Aux is the same (quiet) volume as the phono. FM is still very loud, and seems to be operating normally. I'll try and post a video here later but does anyone...

I'm really hoping to find help here. I recently purchased a Rotel RA-12 secondhand. It was in great working condition then I decided to update the software. Because why not?... Well, it was more complicated than expected since I have an early model that has a usb connection on the back panel...

Hi! I am restoring a Rotel RB-2000 power amp by replacing all electrolytic capacitors. There is only on e question I have with regards the unit I am working on. I am not sure if the main transistors are original and I would like to restore it to its Original glory. What main transistors are...

Hello I'm currently troubleshooting a Rotel RCC-945 cd player. It has what seems to be a ground hum. The noise starts at power up when the relay switch clicks (this relay is located by the output terminals). I re-soldered some solder joints that looked suspicious to the eye. These include the...

Hi everyone. Hope I'm posting this in the correct forum. (I mostly visit the Sansui forum.) I've recently had a friendly local tech perform the famed @Leestereo upgrades to my Sansui AU-555A and it's singing very sweetly indeed. My wife has an little old Rotel RA-210 amplifier from the early...

Hello All, I am working on a Rotel RA1412, when it came to me the right Watts meter was out, after replacing it I noticed the Left & Right meters were not matched. Consulting the service manual I input a 100 Hz Sine Wave on the Aux input, crank volume until I get 9V across an 8 ohm load, and...

Hi, people... new to this forum. I have a 20 y.o. Rotel RSX-972 that worked perfect until the infamous memory supercap gave up (about 10 yr or so). Nonetheless, I still continued enjoying it, leaving it stand-by in order not to lose settings. From time to time, after unplugging it or after a...

I'm looking to replace a cheap amp I'm currently using for my setup. From my research, I've narrowed it down to the Denon PMA-600NE and the Yamaha A-S501. Out of these two, it seems the Yamaha would be the better choice. However, I've just recently acquired a Rotel RB-850 for $15 dollars, and it...

I'm trying to eliminate the last few gremlins in this Rotel. It crackles a bit and I've read that KSA912 gets noisy (and hot) so I'd like to replace Q605 and Q606 on the main amp board, which are listed as "main amp bias compensator". KSA1013 seems to be the go-to sub, but I don't have any on...

Forum friends. I have a little ROTEL RX-200A with the dreaded ground hum. It's 60 cycles, across both channels, and it's like a mouse in a garage - every time I think I have it cornered I'm foiled again. Here's where we're at thus far: Replaced the main amp transistors and four of it's caps...

Good evening, Sometime ago I bought parts to build hypno toads simple phono stage. Well, life got in the way and I was delayed. That said, I'm back at it, but a few questions have popped into my mind that I hoped folks on here would be able to respond to. Here they are. a) I am trying to...

Somebody on my local Craigslist is selling a nice looking little receiver with the brand name Sound, model R-700. Made by Nippon Sound Company. Wood case. Really pretty. Elements of it seem like similar vintage HK or Rotel. Anybody know who sold this brand at the time? Some store brand...

It doesn't play, the buttons and lights are a bit finicky, yet there is nothing visibly wrong internally as far as I can tell. Fast forward and reverse sometimes work, but most of the time they doesn't. What's going on? Has anyone had any experience with this? Rotel RD-870 issues - YouTube by...

What's up folks? I've got a chance to buy a Rotel RB 991 (200 wpc) for $395. Anyone have any experience or opinions about this amp? I currently have a Marantz 2230 and a Sansui 881 and would most likely use one of those as a preamp to the Rotel to drive some Infinity CS-3008'S. There's also a...

Hi, I have a Rotel RA-960BX has been unused in storage for the last 5-6 years. (I bought this 25yrs ago) It was stored as it had a very scratchy channel. Used Deoxit on pots and switches - both channels were working - I put the covers back on & then no channels working. Following morning...

Being 19 and new to vintage audio I was gifted a Rotel RX-603 and a kenwood KR-6030 by my father. I am not sure what the better choice to keep long term would be , I plan on using it with my turntable hooked up to my Q - acoustics 3010I speakers. Just looking for some advise on if either of...

Hi there folks, greetings. Not sure if this is the right space to ask this, hopefully it is. This turntable has a problem with the motor spinning like it spins and stop and it spins then stops. I know the motor is controlled by a driver IC thats AN620 (Almost impossible to get or its too...

My RB-980BX was stuck in protection mode. I checked every component on the circuit board, replaced a couple of resistors that were slightly out of spec and replaced all the smaller caps. I could not find any issues with the output transistors with my DMM or the four large caps so I left those as...

I should probably (definitely?) just walk away from it but I’ve got a lead on this amp at a steep discount. The catch? The fronts don’t work and the seller has no clues (that he’ll share). I don’t need 200 wpc running to my HT surrounds, but even if I can’t get it fixed, can I run front...

Hi, looking for some advice please. I'm replacing output transistors in a Rotel RA913 and need to match them. My cheap transistor tester displays the following for the four transistors: B =62 Uf = 554mV B =72 Uf = 548mV B =62 Uf = 555mV B =58 Uf = 556mV Which number(s) should I be best...

Hello, First off, I am a electrical novice. I guess I know the basic stuff an average person does. I have actually learned most here on AK, but forgive me if I'm not using the correct terminology as of yet. I have a multi-meter. After acquiring some Infinity Kappa 8.1, I was advised on the...

Hi All, I am looking for a stereo SS amp in the 100 W channel range, 4 ohm stable. It will be used to power full range 3 way speakers or to power the lower range on a Bi-Amp setup. In the past i have gravitated towards Rotel RB and Parasound HCA Amps because I think they are a good match for...

Hello all you CD player experts (especially @dr*audio , you seem to really know your stuff!) I have an RCD-855 on my bench right now that belongs to a fellow AKer who has done me a solid. I am hoping to return the karma by troubleshooting his CD player. I have narrowed down the issue, but much...

Hi there, Here's a long intro :) I have been in and out of this forum for years through web searches and am now devoting more time to my hi-fi setup so I'm naturally riddled with questions that seem to be best answered here... So it was time to join! For the longest time I used a Marantz...
