I'm in the middle of building a K2, S/N 6412. ... While doing the Alignment
and test Part 1, I had a couple of readings that were not in specs.
1. Page 48, Setting the AGC Threshold, the manuals calls for adjusting R-1
for a reading of 3.80VDC on pin 5 of U2. The highest R1 would adjust to is
3.60VDC.
2. Page 48 Bargraph Current test. The manual calls for a current reading
Of 0.16 to 0.18. My K2 reads 0.25 amps. That is quite a bit higher than
what is called for.
Any suggestions? Are these readings anything to worry about?

Hi DW,
I'll take a stab at your low AGC measurement. In the past few months a
couple of builders have had marginal +8V regulators on the CTRL board. It's
unlikely this would be causing the higher than expected Bar-graph current
measurement, it is possible.
