two and a half years ago my NAD C350 (purchased new in 1996) shut itself down. I was about to junk it but found a gentleman in Florida who said he could repair it to a better than new state. He explained exactly my options and I chose the full Monty, all new high quality caps, a thorough evaluation of the entire system and new components where necessary and a complete resolder job...ended up costing about $450 -- a lot of labor. I listen to a lot of music and the integrated amp sounds better than it did when new now almost three years later. He gave me a two year warranty on his work...unheard of.

0:12 - "I got a love/hate relationship with these nads." lol.

BAKED! Shango would be proud of you😅

Folks criticize NAD for the cheap build and component quality - which was true - but forget that these were budget end of the HiFi market when new. So, yes, they were built to a low price. The NAD 3020 was just about the cheapest amp that could ever make the cover of a HiFi magazine in the early 1980's - but did! because they were also very good. Many a HiFi enthusiast started out with a NAD because they were affordable to teenage kids and students. No surprise many are tired and baked by now but good restoration can bring them back to life.

Don't hate too much on those NADs. They were built to be affordable. Any thing else on the market that sounded this good, was 3 times the price. Then, this thing is almost half a century old. Show me a piece of modern electronics with that life span.

Nice job Trevor, never heard you so surely, I like it. Owned a NAD for about 3 hours, then returned to Seller for refund. I believe low level is "Mute". I hate light purple Caps. Band aid on finger, cut on thumb, EZ now Trevor. Upper 60's when you 1st turned on.

I bought my 3150 new and still use it. Had a Pioneer SA 8500II before the sound wasn’t has warm. I use different brands but always came back to NAD love the sound.

2k views in 12hours… there must be appetite for NAD repairs!

On the other side, I only use NAD's! Great video, thank you.

Worked on a 3150 recently and 80% of the caps were out of spec.

My second piece of audio equipment was a NAD 3140 back in the early 80's. Still have it. I replaced all the trim pots with Bourne 10 turn VRs. Also the power switch crapped out. I use a power bar to turn it ON/OFF.

In the UK NAD was the entry level budget 'serious' hi-fi amp back in the 80s. They were significantly cheaper than anything else around at the time. Not surprised that the insides are less than optimal.

Those two mains transformers are NOT for dual supplies, well not as in one for left and one for right channel. No, not in NAD land. One is for the negative supply, and the other for the positive supply to both channels. Guess it was cheaper to use two small independent transformers instead of one large as all the others do. I just replace those old trim pots with new multiturn pots, just as you replace all caps...

I was always in 2 minds about NAD equipment, they were impressively loud and had a certain level of quality when new but they didn't have a long lifespan, also the face design seemed a little odd with odd colour choices. A few of my friends had them but I always thought you could hear the quality fading every time they were used until they were changed for something more expensive which was usually Marantz or even Sony because they lasted longer.

Go NADs!

I have read that people like the NAD amps. Never had one.

To be fair, my nads also don't look that great.

That baby got HOT! Darn. Nat a fan of that type of heat sink!

There's still something wrong with that amp. The low frequency square wave response isn't typical, neither is the crooked response at 10khz.

No new episode last Saturday Is there one this coming Saturday?

Why don't you replace the vr's if they are that touchy?

Why did it go out of protection with 4VDC? (Depending on what the customer wants it might be a good idea to just change all the pots.)

I avoid NAD . Ill stick to HK and Yamaha.

Never acquired a NAD for the same reasons......

I think the initial design had a relay coil of 48v. Since 48V relays are becoming difficult to obtain, it seems like the design has changed. Written with Google Translator

I was just given one of these a few weeks ago and was sad to find the left channel is out. I thought maybe I could watch this video and attempt a repair myself but this is way beyond what I'm comfortable doing. I don't suppose you'd fix one sent from BC?

Had a NAD 3240PE in the early 90s. Pretty decent amp. One day a friend brought in a Creek 4140 & the Creek killed the NAD in every aspect of sound quality. Fast forward a few yrs later & yet again i was in a shop where they were comparing a NAD integrated amp with an Arcam alpha amp which was also a budget amp & again the NAD got killed by the Arcam. If u don’t compare, the NAD amps are decent sounding.

Anyone ever put an improvised heatsink or heat shield around capacitors near heat sources? Or would that just help transfer more heat into the capacitors? (Obviously it would have to be done in such a way that the capacitor can still vent.) Also you might want to pick up some gaffer tape to apply to bitey heatsinks like that to protect your fingers while you work.

How do you rate the 3140 build quality compared the 3150 or all they all crap 😅

I've known people with NADs and they liked the sound, but they all broke.

Love NAD equipment, don't love the parts used within. The Japanese made stuff is good; Taiwanese stuff not bad; but the mainland Chinese stuff has the worst parts. I know you hate TK caps, but JH brand caps are even worse!

Just a few weeks ago I changed the relays in my Technics amp. Since the new relays had a higher coil resistance than the originals - and the relays are in series with an LED - I added a parallel 5.7k resistor, giving me the correct current through both the new relays and the LED. That being said, I don’t know why one would add a low resistor in here. Weird.

I have been repairing domestic and professional electronics for many years and in that time I have seen my share of NAD gear. Mostly the Taiwanese stuff, some of the China stuff and a few pieces of the early Japan-produced units. The Taiwanese and Chinese gear is pretty janky. Bad design, low-quality components, cheap caps, cheap construction. Everything runs hot, and as seen in this video the board is scorched from the heat in multiple places. Many NAD amps and receivers have no protection circuitry for the speakers or the output stage and when they decide to let go, they do it royally and take out many parts. People have lost expensive speakers as well due to the lack of protection. Usually when I am tasked with repairing one of these it takes me several hours to go through and replace all the destroyed components and rebuild the unit. Rarely do I have to invest so much time and effort with any other brand of amplifier. NAD just seems to be the cup winner in this regard. Why people rave over them I don't know. There are other brands (Technics being one) which can be had for similar money and are of far higher quality and construction, perform and sound just as well if not better.

Yet another change all the capacitor video BAKED ! like Dan's ( Shango's ) brain

Does anybody know where I can have my stereo work on that does a great job on stereo's .I have a pioneer stereo 1050
