The top output transformer has two capacitors going across what I'm assuming is the primary of it, a .1 uF and a .15 uF both at 250 VDC, I wasn't able to test them out to see if they were shorted or not, but I have those caps on order to replace them to see if it fixes it.

But I do know that the 100uF 12VDC electrolytics and the .02 uF 600 VDC paper(?) caps that were going from the 6BQ5/EL84 Sockets to chassis ground were both bad (they both measured open) and when I replaced both of those caps on both of the 6BQ5/EL84 sockets the radio was still not putting out much audio, the volume control still had to be turned up full blast to hear anything.
