Doepfer A-183-2 MOD?

Doepfer A-183-2 MOD?

2011-05-25 by Dennis Verschoor

Hi List

Is it possible to mod the Doepfer A-183-2 to have a 10 volt offsett
instead of 5 volt?
I wanna mod a set so i can use them to use them to control some Buchla
100  series vco's.
They need 8 or 9 volt to have an audiorange tuning and add a voltage
to that offset.

Cheers,

Dennis

For this you have to replace R1 (220k) by 120k. R1 is the top right resistor
(next to the offset control). I have to point out that warranty is void if a
module is modified by the customer.
