Yes, but not yet - I e-mailed Jeff yesterday and he does not yet have
the new boards or the resistors in stock.

Those resistors are almost never problematic. I would more likely
suspect a poor solder connection or a swith problem. BTW....The new
board has 3 resistors like the old style but the resistors are good
quality. Makes assembly a lot easier.

Yes, it reads grid current. I'm thinking that maybe we should assume
the two problems *aren't* connected. I vaguely recall someone saying
that the voltage multiplier resistors on the Harbach board are
under-rated and therefore prone to failure - assuming I dig in there
and discover that one or more are open, what would be an appropriate
replacement? The value is a total of 14 meg.

like when wiring a new board, you could have a bad wire or
connection. Recheck the connections to the board on the yellow and
orange wires. Also make sure no wires came off the switch or the
meter to the board. They should have used strained wire. broken
wires often the problem.

Subject: [Amps] Harbach metering board in SB-220
I am trying to understand a minor problem in my SB-220, which otherwise
works fine. I originally installed the Harbach board because the HV was
reading low. It fixed that, but quite quickly thereafter the HV
metering failed. I *think* the relative power metering failed at the
same time, but can't remember for certain - a common cause is puzzling
because I can't see any commonality between the two circuits.
Can anyone help me identify components that are likely responsible?
