Vfr350 Posted September 4, 2014 Share Posted September 4, 2014 So I have an older (1980) Yamaha R-1000 receiver that I really like paired with a set 74 vintage vert Cornwall's with recent cap and tweeter upgrades thanks to BEC. My issue is the receiver needs some TLC, it on occasion will have some crackle or just drop a channel. The thing is it pushes those Corn's so nice and it has sentimental value, I'd like the breathe new life into it but I'm finding rather difficult to find anywhere to work with or even responds back to me, can anyone help guide me or make recommendations on this? Tried looking at used units but none seemed to be refreshed and I fear being shortly in the same boat again. Oh I have tried the simple things like deoxit and have even replaced the volume pot that went south. Thanks for your time. Quote Link to comment Share on other sites More sharing options...
paul79 Posted September 4, 2014 Share Posted September 4, 2014 Simply replacing the speaker relay will likely relieve your symptoms To check this, while it is acting up, tap on the black box inside next to the speaker out jacks. If it acts right after that, you have verified my theory. 1 Quote Link to comment Share on other sites More sharing options...

Vfr350 Posted September 5, 2014 Author Share Posted September 5, 2014 Thanks for the welcome, although I did have an account in 2011 that seemed to be invalid now, posted few mostly always lurking. Thats nice in the pic, been keeping an on on that one little worse for wear here. Tell me more about this relay, where can they be sourced? If cheap i'd just do it anyway. Except for the station memory no longer worker (which I can't seemed to find a replacement cap/bat for) everything functions but sure aging. Along with the Corns I have the WF line for my home theater setup which I actually really like as well. I've have seen it something mentioned about balancing the rails on a receiver, whats that about? I've been messing with rope caulk on the Corns, have a new set of binding posts to install yet. Here's some eye candy.. 1 Quote Link to comment Share on other sites More sharing options...
HPower Posted September 5, 2014 Share Posted September 5, 2014 Hey Vfr350, If you are not already a member over at Audiokarma, it might not be a bad idea to look through the Yamaha section... http://www.audiokarma.org/forums/forumdisplay.php?f=173 I have been lurking there a bit since a buddy of mine offered to let me use his CR 2020 while my HK930 gets some work done to it. Seems like a great community, with lots of helpful Yamyphiles. Quote Link to comment Share on other sites More sharing options...
djk Posted September 5, 2014 Share Posted September 5, 2014 (edited) That series had problems, obtain the service bulletin and do it. The mod adds caps in the feedback loop, and you will probably need to replace IC-412, a STK-3106. Edited September 6, 2014 by djk 1 Quote Link to comment Share on other sites More sharing options...

Sounds like you know quite a bit on the subject, are these "mods" you speak of something that can be done with more or less a soldering iron, got no scopes or anything to test w/?

Vfr350 Posted September 6, 2014 Author Share Posted September 6, 2014 So looking a bit more, opened things up, got about or at least half dozen caps that are old, partied to hard and now throwing up green. Apparently it has some indicator lights that I have never seen work in 15 years, some LED, 3 are tiny little filament bulbs, which are so tiny i can't see if the filament is broke or not, but not to worried about the lights. Any suggestions for suppliers for small quantity or individual caps (or should say electronic supplier)? I was also able to locate the speaker relay, popped the cap, no corrosion at least, and found IC-412. Quote Link to comment Share on other sites More sharing options...
Vfr350 Posted September 23, 2014 Author Share Posted September 23, 2014 So I thought I'd post a follow up on this. Although I haven't made any progress on the receiver I decided to try my hand at fleabay and vary least I get a parts unit. Well the turns out my new acquired r-1000 is steps beyond mine. The wood grain cover was certainly more beat up, but most the lights work and the sound, oh man it's like I fell in love all over again with the r-1000 and the corns. Now I can take my time with my original, both need to get a heatsink setup. 1 Quote Link to comment Share on other sites More sharing options...
