Bohmat 78 S schematics

Beitrag von raph36 »

Hello,

i have a problem with my bohmat 78 s, do you have any schematics for this machine,
i think i have narrowed down the problem to one of the led in the little black boxes on the voice card, can it prevent the frequency dividers from working ?, i need schematics for further testing of board including S165 ic, they seem fine by multimeter basic check but i need to be sure. thanks

thank you a lot

Hello,

you can find "Böhmat und Schlagzeug 78 (BA67310)" in

http://www.analogorgel.de/orgel/viewtop ... 67&t=10257

Please notice that you have to register to this forum as well. analogorgel forum is a good source for old Dr Böhm schematics.

Regards, Ansgar

Hello,

the link is pointing to an article in the forum. It contains a pdf documnet (37 MB) as attachment.
I have just double checked it. It is a scan on building instruction BA67310, as always in german.
All schmematics are part of this document.

Regards, Ansgar
