Hello all...
I have been working on restoring an LK-500 NT to operating condition and
it has a funny grid current issue. When I switch the meter switch over on
the front to measure the grid current, the meter goes negative...???? This
happens when the amp is in RX.
I'm puzzled....any help would be appreciated.
Thanks,
Dave
