    Could anyone tell me where I can order a "roach" (neon light and Light-Dependent Resistor) for the tremolo circuit for my 64 Bandmaster?

    I am not having much luck finding one on the net.

    If anyone has any other tips on what I can do, please let this novice amp tech know.

    The tremolo was not working and we detected it was the Light-Dependent Resistor. When removing the shrink wrap from them I broke the neon lamp.[​IMG] I guess after being in an amp for 45 years they get brittle.

    I did find a Light-Dependent Resistor at Radio Shack, but I have had no luck on the net or local stores with the neon light.

    New Sensor is a wholesaler, it's the distribution arm of Mike Matthews empire. It's easier to have a New Sensor dealer order a part (just about every guitar store carries New Sensor products) and the plus side is most will discount the sale price.
