Vintage Synth Repair

Troy and other Wurlitzer 200 owners

Ive just been given a Wurly 200A as well, Ive had the SAME problem. 
Im still working on it. Definately check out Wurlitzer Yahoo Group, 
tons of info there.

the service manual is here >
http://www.interwww.de/web/seipeldata/wurlmanu/

And a complete circuit diagram can be found here>

I cant see how any could charge as much as they are for a photo copy 
of the manual, I could understand it it was an original.
