Buchla 208 easel /Add a CV on the reverb pot mix pcb now

Post by boops » Mon May 20, 2019 5:52 am

I ve just finished to built a little pcb for the function :
CV control of the pot reverb ( VCA)
the reverb on the demo is this of my new card 12,but works with the original too.
I use the rightmost pressure banana .
If interested by a pcb diy or or a ready built ,pm me
New really interesting modulations possible ;)
pcb +bracket +screws/washers 15eu 10 eu shipping WW registerd or 4eu standard

you need 15 mn to build and install it
2 red points on the pots on the pic are the out of the vactrol 5/3
you can bridge the led with a simple jumper
the cv in from a pressure banana
1/4W resistor
1k
1M
1x led 3mm (option)
10k trimmer ,v sensitivity
1x tlo81 (socket 2x4)
1x vactrol xvive 5/3
connectors 1x 2 and 1x3 pin if you want
i take the +15v-15 0 on the distroboard
a quick demo

Nice, Boops!
Can you tell us how you wire up/mount the pcb, and how you feed it with CV?

Thanks
I use (thanks papz for the idea) the rightmost pressure banana .
the pcb is really small,i didnt installed yet
if i found an idea to install a 10k pot ,its even possible to control the amount of cv.

Fed by the rightmost pressure banana
pcb available with the hardware a little ‘L’ fixing bracket
(pic with a prototype on veroboard ) ,15 eu
There is a led to see the CV form,i think perhaps to install it on the panel
it could be handy to check every CV of the easel ,and a trimmer to calibrate the sensibility of the cv ( i use it at max on the sound demo)
