I am in the middle of fixing several mid '70's fender amps. Due to the fact that the filter caps were original I changed them out. I was going to do the same to the bias filter and cathode coupleing caps as well, but they are a style I am unfamiliar with. They are white and plastic looking and smaller than the old cardboard wraped electrolytics I am used to seeing in fenders. Does anyone know if these plastic ones are electrolytic?
Thanks,
Carl
