Haha, thanks. But in all honesty, there are quiet a few on this thread who knows a lot more than I do. I consider myself still a newbe compared to some here. That's one one the things I love most about this thread. Just so much knowledge. We might not have the superstars that Ak have, but I actually prefer it here. Ak is so massive, there are threads upon threads covering each brand. We all can discuss vintage gear in general, whether is a budget sx450 or something like a g22000/sx1980.


Oh, and was it someone here who scooped up that marantz 2500 on eBay for around 750.00? I'm still kicking myself for missing out on that one.

The Pioneer SP-BS22-LR speakers are pretty well regarded, and won't break the bank. They can often be found on sale for around $80-90.

Cool thanks for the tip! There's also some Centrance Masterclass 2504 speakers on sale for $179 that I was considering, they seem to have pretty good reviews as well.

Gratz on the purchase! How much did you shell for it?

Thanks! Yeah it makes for an incredibly solid headphone amp. I picked it up from a guy on craigslist for $75. Everything seems to work well and the exterior is immaculate, there's like 2 scratches on it haha. Was it a good deal? It seemed like average retail for them was around $100-$150.

 

One question for you NAD guys. As I've been listening to it I've noticed that after it warms up about 5 min or so it tends to develop a slight channel imbalance. Things that should be centered are very slightly skewed to the left. I went through and cleaned all the pots/switches with Deoxit and re-balanced the DC offset as per the service manual. I didn't check the idle current yet. Any tips on things that might fix it?

Maybe try the Low Level button.

That's exactly why I almost never go over to AK. I much prefer a reasonably-paced thread covering the general topic of vintage receivers to the massive brand- or model-specific threads over at AK.

Yup thats defo a bargain buddy. Regarding the channel imbalance, 95% of the time this is due to dirty controls but if you've already cleaned them... I would clean them again. Any of the pots/switches could be the cuprite so never assume its only the balance or volume. Also make sure you clean the headphone out as well, gently with a cotton bud or a fine art paint brush can be useful.

 

When you hear the channel imbalance, try all of the buttons and controls and see if this affects anything as you may be able to narrow it down this way. But as far a failing caps go it doesn't sound like this to me, as the sound wouldn't be as good as you describe. A dry solder joint would most likely kill the sound all together not just drop it slightly.

 

Remember you can't clean these old machines enough - oxides can kill audio!  ;)

In general, Accuphase is very highly regarded.  While I can't speak to the value of this particular piece - in the high end world this is one of the top Japanese brands.

Awesome, thanks for the tips! I think that the culprit is the volume pot, as the channels are balanced perfectly at lower volumes, but at higher volumes things start to shift left. So far I've cleaned it about 3 times with dexoit, is there another solution to try or does the pot just need replaced?

This looks to be a niece piece of gear . I am not familiar with the e 303 but I did hear one of their integrated amps a few years back . This one had I believe 180 watts per channel and it was a honey . I thought it gave some of the stores higher offerings a run for the money . But the price on that amp went from around 7 to over 10 thousand  a few years later .

   Of course the 303 came out back in the late seventies .

@ joehalo

Looking good indeed! The stands may be bowing in the middle from weight. Though,:sigh: it's not like they're that high off the ground.
