This is a subset of my main synth blog and concerns the proposed construction of a new synth rack.
The plan is for three rails above in the standard (large format) design of two sloping and one upright (this might be physically divided 2+1). Then a flat one or two rails that slides underneath the sloping unit when not in use (aka the garage).
The problem is that the -12v light comes on but the +12v light does not. Today I tried swapping a power unit from a small, empty case (which had two lights on) to the Rack and the situation stayed the same - one light on the Rack, 2 in the case. I used the same power cord and concluded that the problem must be the three inches of wiring from the XLR socket to the Doepfer unit, but that seems to be ok.
The quest continues.
I might install the Livewire Collection in one of the old cases.
