greyshaw: CR50; C.R. Bridge: Schematic

The cicuit isn't very complicated, so likely can be repaired wihout a schematic.

The Hunts CRB is a similar instrument from 1945 with fewer ranges and neon visble directly instead of driving the Magic Eye. The Hunts CRB also lacks the 6SH7 amplifier. But the schematic can be studied to see the principle of operation.
