[AMPS] SB200 Filament Voltage

A series resistor of 0.1 ohm - or if you prefer, 0.05 ohm in each filament leg.
Easy way to get one is a bit of galvanised guy wire, split down to the
individual strands, and a few inches at most of one strand will do. Adjust to
get the volts right. Makes quite reasonable meter shunts, too.
