Does the wavefreaker run on +-15V as is or do I have to change some Resistors like R4 R6 and R18??

Hi Sascha.

My wave freaker runs on the usual +/- 12V , there is something in the description text on the mfos web page for the pcb , it says the unit must be powered from a minimum of +/- 12V , im not sure what would need changed for 15 V operation.

Dave.

I'm not shure .. cause I'm not an electronic-nerd Very Happy

the Zener Diode Z1 (zener 10V) and the zener Z2 and Z3 look like a voltage regulator to U2 and U3

But I'm not shure if the resistors R4 R6 and R18 need to be changes to get the desired voltage output ....

those resistors are current limiters to prevent excessive current flow through the zener. there's no need to change them for 15V operation.

Hello !

Currently building a Wave freaker Wink
And it is supposed to be installed in a 5U / +/-15V Powered rack (with dotcom & MOTM modules...)

Did you had any troubles running yours @ 15V ?
