    NAD 7240PE - No sound to speakers, headphones very faint.

    Hello all, I have been reading up on this thread https://audiokarma.org/forums/index.php?threads/no-sound-from-nad-7240pe.756209 I have made some progress from when I first started out. The issue is that the amp went silent suddenly, no magic smoke, no popping sounds, nothing. It just crapped...

    NAD 3080 Integrated Amp find

    I happened to look at Craigslist minutes after a NAD 3080 integrated was listed recently. I ended up buying it from the original owner (who had many people contact him after I did--I was first). He still had a couple of brochures that came with the amp. Very nice guy. He thinks he bought it...

    NAD 3020i 220V

    Hello: I just purchased a NAD3020i amplifier as part of a group of older hi fi components. It is a 220V model that a friend bought online several years ago, not realizing that it was the 220V and not the 115V model. Can this unit be converted or re-wired to work on 115V? I do not believe that...

    Nad 7225 - increase decoupling cap values in the amp section

    Hi, I am about to recap the power amp section in nad 7225pe. The schematic calls for 2x 22uf/16v decoupling caps in some section of it. I only got 33uf/25v Nichicon caps on hand so I want to place them instead of 22uf caps. In reality the Nichicons test around ~30uf. I am attaching the picture...

    NAD 7020 repair: emitter resistors

    I had a NAD 7020 dropped on the bench and one of the outputs blew when I was adjusting the idle current with various fixed resistors. So I decided to follow some of the suggestions from other folks (including @leesonic) that have repaired these units and thought I would document it here for...

    Integrated Amp for Thiel CS1?

    Hey everyone. I haven't really posted before and if you all are willing, I need some help. I recently acquired a pair of Thiel CS1 speakers, but my current receiver doesn't cut it (Sansui R-410). Based on what I've read, it seems like I need an integrated amp that has enough wattage for 4 Ohm...

    Used NAD C390DD vs Outlaw RR2160MKII

    I'm in the market for a new integrated with bass management. Budget is around $1,000-1,500. I've found a used NAD C 390DD in my price range. I've also done research on the Outlaw RR2160MKII. I'm torn on whether to take the plunge on a used unit that is higher quality or go new with a...

    NAD 2600 In Protection and General Troubleshooting Advice

    I recently purchased a NAD 2600 that appeared to be in beautiful condition - it was never worked on and cosmetically looked 10/10. It was clear the amp was rarely used and babied. However, once I plugged it in and powered it on, the protection light came on immediately and stayed on. This...

    Which NAD?

    I’m on the market for the old nad 3020 series 20. I see various variations including the 3020i. Which is the best sounding one ? The regular 3020 series 20 or 3020i? From what I’ve read the i series had some improvements.

    NAD S200 Repair

    On the bench today is a rather nice NAD S200 Power amp. It seems that there isn't much information on this amp out there, so I'm putting this thread out there to help any other people who may be experiencing similar issues with the amp. Main issue with this unit is that the left channel has...

    NAD 3020A - volume pot

    NAD Idling Current C326BEE

    Well, not sure if you would believe me, maybe I'm simply deluded. A problem with the NAD C326BEE amplifier. The sound - flawless, but the heatsink is too hot - about 70 C. One of the channels has too high quiescent current. Normal for a while on power-up, then after about a minute rises sharply...

    NAD C352 entering protection mode on volume increase

    I have a new to me NAD C352 in quite a pristine state, sounds great and all functions seem to work correctly. That is, until I increase the volume at around a quarter of the volume knob, not loud by any means, at which point it enters protection mode. I am looking for some advice on what to look...

    Mostly mid-'70s stuff. I like the warm sounds -- and the cool lamps. Sometimes I'll just turn everything on and lower the room lights, whether I'm listening or watching a movie. They make for lovely, soothing (if relatively expensive) nightlights. Anyway, this is the kind of stereo showroom...
