[sdiy] VCS3 EG

[steven_thomas]

Hi,
     I am  in the process of building a synthi A clone. So far I have build
3 VCO's succesfully..haven't tried the EG yet. I have the Hinton
schematics..and I can definitely say there are several errors in the VCO
diagrams  that would  'scupper' your project (these are mix ups between npn
and pnp transistors). These are apparent only when you
compare them with original schemos in the synthi service manual. Now I am
working  from the original schemos, just adding the  mods as I go along.
Personally I would tread carefully following the hinton schemos...

cheers
