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. I guess after being in an amp for 45 years they get brittle.
