Fuse bulb/lamp set (#81/#49) for hickok tube tester
New #81/#49 Fuse Bulbs/Lamps for Hickok Testers
The #49 lamps are specified for 2 Volt, .06 Amp operation and have a nickel base. These are used as fuses to protect the Bias adjustment pot.
The Bias pot and meter are unique and not available from anywhere except from another tester, so using the wrong bulb for the line or bias pot fuse can leave you not with just a burned out component, but an incapacitated tester.
