[sdiy] LM566, SAD1024 and a Paia String synthesizer

[Tim Heffield]

Karl,

If that is the Stringz 'n' Things (1550) I built one of the those many years
ago.  The one thing I remember is that about 10 of the electolytic
capacitors were bad right out of the box. If I recall there was no sound at
all on the notes connected with these capacitors.  Once I changed the caps
out it worked fine.  If I were you I would change ALL of the electrolytics
in the thing.  I have schematics for the unit that I can scan if you need
them.  Does the top octave chip (MK50240) work?

Tim

Hi list, just picked up a Paia Stringsynthesizer from
a flea market for $40 and it turns out the chorus is
busted. The whole thing is driven by 4 LM566's where
at least one, probably two has blown. These seem quite
unobtainable and i'm thinking there has to be a more
"modern" and cheaper way of getting this thing
running. Any thoughts highly appreciated!

Thanks

Karl
