I'm up to page 43 in the assembly manual. I would like to know if the following measurements are within tolerance. When I plug in the ribbon cable between the K2 and KPA100, the current increases by 240ma. With the voltage tests I get the following: D13 cathode - 164V U4 pin 8 - -29V The other two are zero. Tnx for any feedback. Tony Tony N2TK #3481
