Vintage Synth Repair

Hi Colin

W D Greenhill at  <http://www.wdgreenhill.com> www.wdgreenhill.com claim to
have these in stock.  I know Bill and his son Nigel, the owners of W D
Greenhill very well and they are the most likely to have this component.

Mention my name, Brian Davies.

Regards

Brian G3OYU

Subject: [vintagesynthrepair] Clef String Ensemble AY-1-0212

 

  

Hi Guys,many years ago(34 to be exact) I built the Clef Products String
Ensemble from articles in Practical Electronics.This was one of the best
analogue string machines I have ever heard but I sold it shortly afterwards
to raise money to build the Clef Piano.I now have the urge to go back to my
youth and build it again.I've managed to get hold of the old magazines and
nearly all of the parts but the ones giving me problems were the BBD chips
and the top octave generator.I've now got the TDA1022 BBD's but can't find
the AY-1-0212 top octave gen.Does anyone out there have one or know where I
could source one.As a last resort I could use the one out of the piano but I
don't really want to keep swapping it about.Could I slave the O/P from the
piano tone gen to the string ensemble via an extra set of buffers to the
divider ccts as I am thinking of housing both instruments in the same
cabinet using the same keyboard with an extra set of key contacts.Ideally I
would like it to have its own tone generator but that depends on if I can
get the chip.Any help gratefully accepted Regards Colin.
