I have looked a bit more into the coils today, I am getting a variety of different ohm readings after testing each connection on the coils. The only problem is that I don't know the values of each pin coming off the coil. I have a schematic, but no values for the coils. I know you guys stated that a low number is good, but on the coil that connects to the R.F. stage 44 tube is reading 1.47M ohm on several pins and 11.1 Ohm on one pin, perhaps I am testing it wrong. Could anybody tell me the proper way to test these pins coming off the 5 coils. And if anybody has values to follow from that would be great.
