I am at a loss to figure out just what type of cap to use, with or without a diode or extra resistor and if the cap should be film, oil-filled, a motor starter type, etc. Currently I am using a small box at the end of a very short, heavy-duty extension cord that contains a few power resistors, an on/off switch, an "in use" light, a recepticle and a dial-type switch ...

I checked the coil again and it checked at 3k, is this correct? It seems a little high. The Radio picks up some signal, not very loudly nor clearly. It sounds distorted. Not bad paper cap distorted, more like it is in the speaker. Any suggestions? Thanks.

It doesn't work. I found out after i disassembled the system it has a main circuit board that looks intact. no blown parts visibly. I checked the bridge diodes and they look functional. One funny thing is if I insert the power plug into the power strip repeatedly it will turn the amplifier on and I can play the amp. What ...
