| - | ====== Omni D S-Meter Lamp Mod ====== | ||
| - | **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: | ||
| - | |||
| - | -Remove CM47 Bulb. | ||
| - | -Cut out resistor on base of bulb. | ||
| - | -Install new bulb (1892). | ||
| - | -Install 10 ohm resistor as shown. (Diagram shows the new resistor connecting from the red wire on the Mic/Blanker pot down to the lug on the lamp.) | ||
| - | |||
| - | 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. | ||
