Hickok 600A meter replacement.
One each Hickok 600A tube tester with a damaged meter.
One each Simpson 100 uA taut band meter movement. Scan the original meter face and reduce 66% to fit the new meter face. Put a 125 ohm resistor across the meter movement and a 130 ohm resistor in series with it. 500 uA full scale and 230 Ohm series resistance total. Presto, a working Hickok tube tester. Jeff |
