Yamaha CS80

On the specific point of tantalum IC decoupling caps, is there a consensus
to avoid them, as I have heard?

Hey Max,
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)

Cheers,
TOM
