Hickok 750 Dynamic Mutual Conductance Tube Tester

Good physical condition but meter does not work (damaged coil), unit powers up and seems to work otherwise. Cracks in circuit board were repaired very well with epoxy and perfboard. All switches, potentiometers, rheostats, and sockets were cleaned a few years ago, electrolytic capacitors were replaced, a grounded AC cord and fresh lamps were installed. Has correct tubes installed in both rectifier sockets. Two top cap jumper cables included, comes with photocopies of manual and tube test data including supplements for foreign, European, and obsolete tube types, has an original tube chart but no roller mechanism.
