Greg, I am still wondering about one thing. Do you receive SW when the 44 RF tube is completely removed from its socket?
If you only receive the SW signal when the 44 is plugged in, then it is possible that the RF stage is oscillating and providing the local osc signal for the SW reception.
So, do you hear anything with the 44 out of the radio and the antenna connected to the 36 top cap? You should get good broadcast reception if the oscillator is working properly.
If you hear nothing but noise then the 36 osc is not working and the SW reception is most likely caused by the 44 stage (which is a separate problem).
