Picked up a new CR-840 a few weeks ago and after opening the cover and plugging it in I determined that it was really trashed. Layers of dust and dirt covered everything (including the infamous pre-drivers –parts with no replacements)!
Also, the left channel seemed weak – really weak – and no lamps. I was about to kick it to the curb, but decided to give her a chance. So I started vacuuming, cleaning, detoxing, and lubing. I brushed and wiped everywhere possible then took the CyberClean compound to it. After a few hours things started to look better and the sound was better.
More deox and lubrication helped and the left side came back! Removed the knobs and dissembled the fascia. Got everything cleaned up with Windex and Magic Eraser and by now it was looking really good and sounding clearer! Installed new lamps (green glow in the dark is cool!!) – the old 840 was almost good as new!!! Sounds great now and looks almost new.
Still need to deal with the Yamaha pre-drivers – any/all advice is welcome. I read that heat sinks may help preserve them?? Is it really true that there is no way to replace these components??
