Gents: in building the KPA 100 I am at the Bias Current Adjustment postion of the manual.I have a DMM in seies with my power supplu and the KPA100 as instructed on page 49 of the manual. I made sure that the PA was on and set the K2 into CW test using the VOX button sot that the C was flashing. I then set the power to 0.1 and up to 119 and back to 0.1. The curerent reading I got on my DMM was 530 to 540 MA. I then tried to set the bias current toa target current but could get no change in readings on the current by turning R6. So I am at an impass and stumped as to what to do next. I feel certain that this bias current is too high and something is wrong on the KPA100 board. Would appreciate some suggestions as the what to check nect. Thanks is advance Ed, AE4EC
