I have observed nuvistors in both of my versions of these rigs
but I cannot find schematics that show them.

The Edebris site must have the older versions of each rig.

I can't read the serial # on the Comm IV.

My Halli is the SR-42A model.

Anyone have an answer, please?

Thanks & 73, DavidC KD4E
