I just fired up one of these Ver 1.0 Drip Boards for the first time tonight. The unit is passing audio but I'm having a bit of trouble. I'm using the Allied power transformer and Sowter In/Out transformers.
My first question is pretty basic and if I was second guessing myself right I should know the answer. Across the 6.3v heater supply I get 6.7v but between each winding and the CT I get 3.3v. Is this correct?
I'm also getting some DC voltage across the Gain and Reduction pots making them scratchy and the front panel a bit microphonic. Any ideas where to look for the cause of the DC?
Thanks.

So far I have 53v across NE2 (I haven't messed with the zero adjust as I have no vu meter yet)
I'm getting 19.8v dc across the compress/limit switch and to pad #1 of both the Gain and Reduction pots. Voltage on the wiper changes as you move the pot obviously. I also read this at R7 and Pin 7 of the T4b but no ac voltage like in the chart.
Should I be getting 65.7v dc at Pin 5 of the T4b?
