    NAD 3155 outputs one channel only

    Hi, I have a NAD 3155 that has worked very well over the years. Now though the left channel has stopped working and I thought I'd give it a shot at diagnosing it. I have opened it and cleaned it with air and electronics spray and it helped with crackeling in the audio knob, but still just...

    Hi all, First, my apologies if I'm in the wrong forum. It's been many, many years since I've visited the site. Good to be back. A general question about repair and value. I'll try and keep this short. 5+ years ago I purchased the gear listed in the headline (minus the Luxman - that was a...

    HELP! NAD 7240PE tuner

    Hi all, I have a NAD 7240PE with a tuner problem and was hoping for some help troubleshooting. The amp all works expect for the FM band. I get no sound and not auto seek or station lock. The AM side seems to work (I can pick up stations). But the seek is a bit touchy. I thought it might be...

    This sounds weird, but show me pics of your feet! (NAD 3125)

    Good morning, I picked up an old NAD 3125 integrated and 4125 tuner yesterday. The stock feet are missing; they were replaced with square, clear rubber, stick-on feet that are starting to peel off. I'd like to go with stock style replacements, or something similar. So...anyone with a 3125...

    Dead NAD 106 preamp

    Hello, First post here - thanks for reading! :) I've bought a used NAD 106 preamp. I know it's nice, but not this one - is hums all the time when connect to amp or active speakers. Sound like 50hz hum from the psu. Everything looks very nice on the pcb and no visual errors to be seen, the pcb...

    NAD 7240PE recap, rechip, reconfigure & repurpose - a.k.a. Duncan's Folly

    Here's a story about how a recap job on an old NAD receiver got out of hand. This 7240PE has been doing duty as a preamp only. A while ago I decided to pursue optimizing the preamp section by the usual means: improving power filtering and signal coupling, updating op-amps where applicable. But...

    NAD fixers: Any usual suspect TRs? 7250pe crispies

    Hey gang, NAD's making low level intermittent static in one channel. Feels like a noisy transistor. Been sitting on bench for awhile but memory serves it wasn't input nor volume dependent. Before I get serious I thought I'd reach out to see if anyone could help this chimp brained AKr. Thanks Carl

    NAD Radio gain Help

    HI all, Problem: My phono stage on my NAD 7130 amp is quite a bit quieter then my radio (FM) section. So when I go from phono to tuner - I could damage my speakers with the jump in volume. (My turntable is MM and the amp is set to that) Is there any way to turn down the radio gain in the amp...

    Speakers for NAD 7030 Solid State Receiver

    Hi folks, I have a NAD 7030 receiver from 1977. I just had it refurbished and it sounds amazing. I’d appreciate advice on what speakers to pair with it. It only puts out 30 watts per channel, so I assume I’ll need to get very efficient speakers. My budget is roughly $1,500 for a pair. The room...
