Vibrator - 12 Volt, 4 Pin, Negative Ground

To determine compatibility you would first have to determine three things regarding your unit and it's vibrator: Voltage, number of pins, and whether the vibrator is a positive or negative ground.

The unit I bought is a 12 Volt but the GP 11 drops the voltage for the original vibrator to 6 volts. I plan to remove the dropping resistor so the new unit would have the 12 directly.

We do not offer technical/repair service here at AES and as such would not have the reference materials to determine whether your transceiver is negative/positive.Rest assured we do carry vibrators in both ground types to suit your needs when you do learn your grounding type.

We simply do not have the resources or reference materials to determine what type of vibrator goes in your radio. You would need to determine, voltage, number of pins, and what type of ground your radio has.

We do not know if this will work with the Firvox Type F-93.
