AM100mV Meter

Make your amp look really vintage cool with this vintage looking analog meter movement. 100mV full scale movement is perfect for measuring directly across a 1 ohm power tube cathode current sense resistor. Or, you can knock down the B+ with a resistor divider and display B+ from 0 to 1000 volts. Put in a switch and do both. Requires 2″ round panel cutout and 4 bolt holes. Cardboard template included with meter.
