Does the static occur only when turning he tuning knob or is the static constant?

Does another radio located in the same location and plugged into the same outlet do the same thing?

Ohm the antenna coil (primary and secondary).

Another trick is to touch the stator terminal of the RF Amp section of the tuning cap with a long wire.
The section with smaller plates is the oscillator section. Don't touch that one. If you get a clearer signal, then troubleshoot the RF Section. You may have an open RF transformer coil (antenna coil). You may have an open secondary in the 1st IF transformer. I had that happen to me on a 1940 Mantola battery portable.


I previously said that most AA6 radios have very similar schematics. This one has a glaring difference, in the capacitive coupling between the converter and the RF amplifier, and the lack of a tuned circuit between the two.
You likely have the correct tubes in the correct sockets, otherwise, the radio wouldn't play at all.
