From the Ten-Tec Reflector June 1, 2002
I just dug through my Omni folder and found a Ten-Tec modification for the Omni meter lamp.
The modification sheet came with two parts, a 1892 bayonet base bulb (14.4 volt - 0.12 amp) and a 10 ohm, 1/2 watt resistor.
Here are the modification steps:
In the circuitry, the lamp and the resistor wind up being in series and across the 12 volt line. This is where I used the 33 ohm resistor instead of the 10 ohm that Ten-Tec supplied, and I've never lost a lamp since!
I'm sending a copy of this to the Ten-Tec reflector in hopes that it helps someone.
