i just purchased the DIY kit #2 from analog haven and i am having some weird issues with
it.
only a few modules work correctly, a few not at all and a few with a very bad ground hum.
the doepfer mixer and spring reverb work fine. the cwejman and dual LFO do not work at
all, they just hum. The cwejman dual filter works fine
and the doepfer 188 noise sorta works, it takes about 45 seconds to start working and
has a very bad ground hum
I have tested them after having used the DIY kit in a doepfer portable case and they all
work fine.
to the best of my knowledge i have bus board connected correctly -- i tried it at analog
haven and tested it with a doepfer high quality osc and it worked fine. then did not touch
it after that.
here is a link to a picture of the wiring to be sure i got it correct:

The power supplies are matching and output 12VDC 500mA, and all the leds on the bus
board light up correctly...
really not sure what is going on, has anyone else had this issue Any help would be very
much appreciated.
Best,
