Right now I get a slight garble in the audio and I don't receive anything on the dial except for pumping in a signal from my AM transmitter. I have located the one rare tube and the other common one, so I am excited to see if that's the culprit. I heard the rare one, the 20B8GT, is not uncommon to find weak or dead.
