Never mind. I forgot to turn off the fluorescent light fixture on my work bench.......it causes the Quickie to hum. I knew this already, but forgot when I got flustered about the A5/B5 pin voltage not measuring correctly.
FYI - if you wire up your Quickie per all the manual corrections, I think the A5/B5 voltage should be measured at A1 or A7 and B1 or B7. My Quickie measures ~2 VDC at these pins.
I love Bottlehead kits, but the errors in the manuals can drive a person crazy!!
