There are 1ma movements with about a resistance of around 30 or so ohms.  Full 
scale voltage is around 30mv.  You can reshunt any meter to make it work.

 Are the panel meters (plate current, and grid current/HV) considered a milli- 
or micro-amp meter or a voltmeter? No info in the manuals. They are (per the 
schematic) both effectively across sub-ohm shunt resistors (grid current is 
across the sub-ohm shunt resistor to ground; plate current is across the 
next-up sub-ohm resistor towards the HV PS negative terminal.)

Thanks for any suggestion/info
