Thanks, can't hurt, then again I'm a clutz with this stuff and have destroyed a few LD players by going in solo. Reino - Sony ES has a good reputation, I can't find any info on faults like this with an 808. Thanks for your thoughts Zeta, a guy on AVS forums also basically thought heat was the problem, I'm not so sure, the problem first presented itself on the first CD I played. Thanks guys for your posts, very nice of you all. Yeah it's been a tough year and I thought something was finally going to go right when I first heard this amp, but nah.. haha

Thanks LD Fan. I took the unit into the professionals in my area. An old school hi fi shop with 40 years experience. They had it for three weeks and reflowed a ton of dry/cracked solders. They charged me $250 and I got it back the other night. First thing that happened when I fired it up again was the audio was dead on the left channel for about 30 seconds, then it was good for the next hour. Then some of the same old problems came back, fuzz on both channels, audio drop outs...FFS! Then for the last few days she's been getting better!? Less problems, more stable sound. Though not perfect yet, better than before. I think I probably need to take it back for them to keep working on. Or get ebay to agree to the exhorbitant cost to ship it back to the seller in Germany. Anyway I have started another thread on how to set this up, based on wether I keep it or not (it still might be going back to the seller for a refund)... Getting this amp that I've wanted for a decade has been a saga. Murphy kicked the crap out of me on it. From returned transformers, to wrongly addressed packages, to missing remotes, to the amp not actually working despite paying a top price, it's all been a test...

At least you're making progress and something is improving now. I just inherited a broken Marantz, NR1605 and it's frustrating me since I can't quite figure out what the issue is. Overall, the machine looks clean inside which makes it harder to find where the problem is (no burn marks or funny smells to give me a hint). Anyway, it sounds to me now that maybe you have some dry caps to deal with now. I don't think you have any issues w/ transistors, diodes, resistors, etc. since I'm under the impression that if they fail they just go bad right away (but I could be wrong too). forper wrote: Anyway I have started another thread on how to set this up, based on wether I keep it or not (it still might be going back to the seller for a refund)...

From returned transformers, to wrongly addressed packages, to missing remotes, to the amp not actually working despite paying a top price, it's all been a test... Sometimes that's what we have to deal with. I always wanted a Mitsubishi, HS-U80, S-VHS VCR and I finally got one about 23 years ago that had issues. At first I was frustrated because I couldn't quite figure out what was wrong with it. However, after some patience and actually a lot of luck, I got all the bugs out of it and it's been fine ever since (although I think I need to fine tune the video settings). I would never give it up. Now the problem.... it just sits in my rack and rarely gets used. I treat it more as a water cooler topic at this point but I think I will be making a tape on it @ some point for a project.
