I am fairly sure that during the 2 series, S9 is 50 uV. The others here will correct me if I¡¯m wrong. I can¡¯t remember if the 2-A had any paper capacitors (the 2-B has film capacitors that look similar to paper ones). If the can cap isn¡¯t leaky, keep it. I haven¡¯t seen a 2-B with a bad one, for some reason.?

I have a very clean (for a 60 year old radio) 2-A that I'm checking out for selling. It has been my bench receiver for years and seems to work fine.? All voltages check out fine.? for a 50 uV signal on 40m, what should the S reading be? I'm getting S7.? All caps are the original and I've peaked the 455 KC transformer.??
