[Boatanchors] Millen 90651 GDO Problem

[Bill Stewart]

Hi all and a Happy New Year, 
I tried to use my Millen GDO a few days ago and the meter slams hard 
to the left. The 9002 cks w/o any shorts, but is abt half the reading it should 
be on a Hickok tube tester...don't have a spare to try. This GDO has a pot 
on the left side with a nice chrome knob. It varies the meter reading. The pot 
does not show up on the BAMA schematic & looks to be factory installed. 
The s/n is 265. 
  
First, any ideas what the pblm might be and secondly, would anyone have 
a schematic & parts list of this model that shows the pot and could send me a scan. 
  
Tnx, 73 de Bill K4JYS
