Hickok 539B Tube tester, sn152 1031 SOLD OUT

The line meter and bias meter movements work fine, but there is no bias voltage displayed (line voltage displays correctly). The main gm meter deflects slightly on power up, but showed no readings with any tubes tested, and the mechanical Zero adjust works. The gasket on the gm meter was replaced with weather proofing tape as a temporary fix. Not sure if the meter is open or not.

The interior is clean and original, and the few electrolytic caps in the chassis should be replaced. The switches, transformers and sockets are in excellent condition for their age. It's been stored in an air conditioned space.  
There are solid state upgrades available for the rectifiers, and digital meter upgrade for the main meter.  

This Hickok is sold strictly AS IS, for Repair or parts, with No returns, warranties or guarantees of any kind.
