Vocoder PSU Front view
For the Vocoder PSU I didn’t make a new PSU. I just took what I have at hand. So this is a very short post. I just took three of my ultra low ripple PSU with LM350 and put them in a frame. Two are daisy chained for the +/- 15V. The third is for the 6V which is needed for the display unit.

I wonder how are interconnected all the three modules, in the pics I can’t see if the modules have a bonding point or are grounded. The outputs are floating? There’s no 50hz hum?
Hallo Isidoro,
all ground points are connected. The wiring is done when the module is put in the case. It is not shown on the pictures.
