WORKING USED HICKOK 580 TUBE TESTER

TESTED / USER MANUAL COPY

RARE TUBE TESTER

CLEAN / MINT

\"In pictures I tested a Brimar Brand 12AU7. I tested using Plate voltage 250V and Grid -8.5V. Results are in concordance with Amplitrex measurements marked for the tube. the measurement is shown in two different scales (3K umhos & 10k umhos)

I also tested using Plate voltage 300V and Grid 0V. Gm measurement is in corcordance with RCA Manual RC-30 ( Gm NOS= 3100)

Finally I tested 6L6 using Hickok chart configuration

The Hickok 580 one of Hickok\'s most advanced testers. It is very similar to the coveted Triplett 3444A. Unlike most of Hickok\'s testers, this one has several Plate and Screen voltages available for setting up tubes at or very close to tube handbook settings. This tester is far more advanced than the 539B or C.
