Thanks, Lou. First thing I did - the shunt is OK.
I should add that power on either tubes is down, with max at 1,500 Watts into
a DL. Plate current at full power is about 800ma @ about 4500 volts. Idling
current about 100ma, with bias measured at CT of fil x-former at about 13 volts.

My problem is: when the amp is keyed (no drive) the grid meter slams forward
against the peg. Does this with two tubes. Disconnect the filament leads and
it does not budge.
Check to see if your grid shunt resistor/s on the grid meter are opened. Lou
