In pre wiring preparation, I have been testing for resistance and continuity of my boards between +/-V and Ground. A bunch of boards are fine, but my pair of VCOs are showing continuity between +V and -V. Not good!!! I am testing them with the ICs out and the tempcos have not been installed, though it seems to me it should not make a difference. No short between ground and voltages. Hours and hours of inspection have yielded zilch for a perceptible bridge.

These are REV01 boards. I seem to remember the MFOS site saying "far less kludging" when I bought the boards, but now the site says No kludging. Hmmmmmmm...

Was there ever a trace cut Kludge on the VCO PCBs??

It doesn't sound good. Check all + and - traces for shorts...
