Subject: R: [yamahacs80] Re: My own CS-80

Could be just me Max - I've always said: "if it wasnt for bad luck I'd have no luck at all...!"

Actually, one of my 80's has had the 4 VCO chips blow. The other has the two VCO's that won't 'scale' and I think both have blown a VCF-EG chip. Still need to investige the latest fault on the one downstairs.

Cheers,
TOM

Sometimes-it happens also with super modern hi-tech devices of today- it could have simply be born under a bad star...it sometimes happens :-(

Many years ago I had a tantalum on one of the TSB boards go short (blowing a fuse every time a certain Bb key was hit... a real bugger to trace that was!)... and currently in one of my 80's I think I have a couple of VCO chips that don't scale perfectly during the tuning procedure. They work and play OK but are also probably on their way out...!?! Oh, and one preset bulb needed replacing...;c)
