Re: Did any of your CS80 *restorations* involve new IC's...?

2007-09-24 by blchrr@homecall.co.uk

Hey man, 

The guy whos done my unit, Kent Spong, has a load of spares, loads of voice 
cards etc. I dont think he had to replace any of the IG series chips in 
mine. I dont think he would sell any of his spares though, all that stuff is 
like gold dust...
You could email him and ask, im pretty sure he is on this list, dont know if 
he has time to check his emails though, im sure he is wadding knee deep in 
20 or 30 CS80s at the moment (NO im not kidding lol...) 

Its definately worth having some of your own spares kicking around, i have 6 
spare voice cards that came out of a CS60 with some issues. I know some guys 
will hate me for saying it, but if you find a tatty CS60 or CS50 with 
problems, it would be a great parts machine for a Cs80.. Only problem is 
CS60s are not cheap any more.. Ive stripped out 3 not working CS60s for 
parts in the last 2-3 years, sold some voice cards and stuff on Ebay and 
kept enough to keep my unit working..
I also lucked onto some cheap TRG boards from an 80 a few years back (they 
are the aftertouch boards, with loads of VCAs on them) so i have a load of 
VCAs too.. I think they were about $75 a board..
Christ knows how anyone could strip an 80 though... 

But there is no source for nos Yamaha ICs. They are long gone.
It remains to be seen if Yamaha will fabricate some new ICs, there was some 
talk a few years ago that they might consider doing a run of the later spec 
VCO chips, highly unlikely me thinks, but you never know.. 

I wonder if voice cards could be made that could be drop in replacements 
based on discreet components? Juergen, Scott, Kent any of you guys think 
that could be done? 

Cheers,
Rob.
