2-A S-Meter Reading

Clark WU4B All Messages By This Member #71056 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.??
Steve Wedge, W1ES/4 All Messages By This Member #71057 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.? 73, Steve Wedge, W1ES/4 Time flies like an arrow. Fruit flies like a banana.
