Well DUH, I guess the pot would show a short with the S-Meter inline
although it should show at least 100 ohms, boy do I feel stupid. I removed the meter
zero pot (R-29) and checked it out of circuit (like I should have in the
first place) and it checked fine. R-30, a 27 K ohm that precedes the pot,
measures around 850 K (thanks Joe, W5JDY). I believe the leakage to ground is from
good 'ol paper bypass caps leaking along the 280V B+ line. I guess it's time
to start buying caps and resistors.
Thanks all and 73! DE N5MCJ, Jerry
