> That's sounding new to me: all the people I know who owned or has a CS in their ballpark had very few problems with the custom iCs: if my memory serves me well, only a friend from Germany suffered from a VCA malfunction years ago but luckily fixed it; in all other cases just CMOS, caps, PSU issues but nothing that needed a full replacement of the custom chips, a friend of mine from Italy had 4 CS80, sold many of them, restored all of them, each one had few or no problem to ICs ; did the not-so-in-full-shape baby had another owner? 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 :-(

> In my CS80's it's the custom chips that I have had the most problems with!! Up to now I have had 4 VCO chips and two VCF-EG chips blow. 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)
