+1 on Ron's comment on lowering the cathode resistor value. I fixed up a 19B about a year ago. At the time I put a 10K resistor there. Last week I powered it up and tried tuning to a station at 610. However, all sound stopped as soon as the dial went below about 720. I tried another 36 tube, but that didn't really help.
I remembered seeing other posts where Ron said that this resistor could be as low as 7500 ohms, so I tried it and it worked great.
Thanks Ron!
