Well I just ran the shadowmeters from a LV supply and both do function properly. After bending the light source to get the shadow centered it takes 10mA for full deflection on the meter with the 850 ohm coil and 15mA for the one with the 1.4K coil. The 850 ohm unit was the one in my original chassis so I will use that one.

I also noticed quite a few differences between my chassis and the donor chassis including the tuner dial and band selector switch. I guess these were running changes. Seems odd that they changed the sensitivity of the shadowmeter by 50% and it is used in the same circuit.

Thanks,

Steve D
