Thanks kevin and billh - after I wrote this here I kept searching and found a site specifically on rebuilding the 2270 including replacing the caps and some transistors, plus how to clean the pots. I'm good with a soldering iron/pencil (used to build heathkit computers and printers for the local store) but I'm not sure I want to risk damage to the 2270 so I might try to find someone locally who is good at refurbishing them. I will give the pots a crack first.
My immediate problem is that my Denon 2802 that I use in my home theatre recently started putting static out through the rear channels - like it is stuck on the test tones - so I now have to hunt for a replacement. My choices are either another Denon 3311ci or a Marantz sr7005 (since I'm familiar with both brands and liked them while I had them). My reading of reviews suggests that the more expensive SR7005 is a Denon 3311ci in Marantz clothing - the rear panel is 95% the same and with the lid off the upper two circuit boards look identical as do some of the large caps poking out from underneath. - so, I'm at a loss and leaning towards the Denon 3311 - but then again the Dennon 991 on sale this week at Future Shop is similar to the 3311ci but with a few bells and whistles missing - like zones (that I don't need.). I don't see a clear winner - I've yet to see a side by side comparison of the denon vs marantz. Some of the better sound shops won't carry Denon because the quality is now "clouded" by the fact that Future Shop is allowed to sell the low end units.
So basically, I'm confused and undecided. Does anyone familiar with decent quality surround sound amps have any suggestions? Speakers are all Paradigm. Reasonable suggestions would be appreciated. Tinnitus is messing with my hearing so I don't want to go REALLY high end but do appreciate good sound.
Just thought I'd ask this here as it seems there are a bunch of audiophiles lurking here in the woods. Thanks
