[TenTec] Centurion Plate Current Meter

["Michael Tope" <W4EF@dellroy.com>]

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. 

Thanks,

Mike, W4EF...................................
