Hey all. I have an sx-1050 and was wondering if anybody has found somebody in western/central Massachusetts or new york city that they would recommend to go through an old receiver and check it out. There are absolutely no problems with the receiver at the moment, but some preventative maintenance never hurt. I'd prefer to drop it off as shipping it is a disaster waiting to happen.

There's an AK member in Marshfield Ma, No. Shore, but may be too far?? He works in Quincey which migh be closer. You could PM him - Grateful -- He would tell you if he could help or not. Hope I'm not violating any forum rules here.

Not sure if this would work for you or not, but, In House Service Company
12 Technology Drive, Ste. 13 East Setauket, NY 11733 was who I used. I found a Pioneer SA9800 and shipped it to him for a once over and preventive maintenance. Was very pleased with the results. Good people and fair. Check their website out if interested. Good Luck

I've found that there is a little static coming out of the left speaker during listening. Any ideas of what to do to check it out? I used deoxit in the front end of the receiver (sx-1050) and sprayed the rca connections from the pre-out to the amp in. Also sprayed the speaker terminals and it didn't get better. Any ideas? Only left speaker. The scratchyness comes and goes as well so it's not all the time.

checkout http://approvedaudioservice.com,they're in litchfield, conn, should be close to you.

they've done work for me, rehabbed my nakamichi 600. did a good job.

thanks for the note. Ill look into that. I swapped my wires to speaker B and the static is gone. I tried to reconnect the wires to speaker A input a few times but no help. How can I clean speaker A connections? I sprayed deoxit into the terminal and tried to clean it but it didn't help. Any other ideas?

Hey all. Today I was listening to it and I noticed the right channel wasn't coming in very well. When I looked closer into it the right channel is extremely weak. Can anybody help me figure out what's wrong?? It's coming in soft and full of static. When I removed the speaker wire ends they came out and look reallllly dirty. The copper looks black. Maybe the terminals need a good cleaning? If so how do I clean in there? I sprayed some detoxit a week ago but couldn't figure out how to really clean it up in there as the Q-tip didn't fit.

I forgot to add that I tested speaker hookups A and B and both were the same which leads me to think it's something inside?

Dirty switches, almost certainly.

Hey EW. That's what I thought. Can you give me an idea of which switches you think and where to find them?

If your speaker wires came out black THEY are dirty and should be cut back to new wire. Solder the individual wires. This will help delay (by a good long time) oxidation of the speaker wire ends.

As for the speaker hookups on the unit itself, find a TINY bottle brush (nipple brush only smaller) and run it thru the terms with cleaner and then again with de-oxit.

The switch contacts you need to get at are inside, behind anything that goes in/out , back and forth or roundy-round.

You will have to open up the case, and some of the more deeply buried stuff in the front panel needs to have the modules of the assemblies mechanically removed (but NO wires disconnected) from the front panel to get at them. They are MADE to do this, but sometimes it takes a little headscratching to get them out.

That's why deoxiting is usually a DIY project - it is labor intensive.

What do I use to remove the volume knob? It looks like an allen wrench bolt, is it?

Carefully, yes....can't remember the size but do a little searching. I had to go out and buy it.

Can you give me an idea of which switches you think and where to find them?ALL switches are suspect. Signal path is through most of them at any given moment.

Yes you really have to get in there to access opennings to those switches/pots. It's a partial disassembly process. Just tak your time and go slow. It's well worth it.

There was a great post here somewhere with pictures of the disassembly process. Do a search.

Makes a huge difference :yes:

I looked around and couldn't find one. I did, however, find directions for deoxiting. I'll try again. It is safe to spray deoxit into the power switch? I didn't do that last time since the instructions I found didn't say to do it or not to do it. I'll check around for one of those small brushes.

Sorry - it was a deoxiting post with pictures of disassembly.
