Are u saying the VCO does not function, that it's silent and it makes
the PSU buzz, or are you saying it operates and the PSU busses along
with it?

Which model to you have:  the Rev 1 series or the Rev. 2 series?

If 1:  Are you making sure the red band is UP on the module side and
conversely the correct orientation on the A. Sll side??

If it is operating, just making the PSU buzz you're probably very
close to the edge of the current rail on the A. Sol power spply.
