>From your description everything is normal except for the erratic reading of
the current meter.  I would check the meter, and the associated resistors in
the meter circuit, for defective component or cold solder connection.   PULL
AC PLUG and BE SURE HV IS DISCHARGED before making any checks.  HV IS FATAL

Subject: [TenTec] Centurion Plate Current Meter

I am checking out a Ten-Tec Centurion 422 (2 x 3-500z)
amplifier for a friend. This morning I fired it up on 20 meters
(into a dummy load) for this first time. Everything looked
good (output power, tuning, etc) except for the plate current
meter. For some reason the plate current meter on this unit
overshoots horribly (close to full-scale) and then oscillates
back and forth a few times (~+/- 200mA) before settling to
the key-down reading. Is this normal for this meter? The
grid current/multimeter doesn't do this, nor does just about
any other meter I ever seen.
