I tracked the short down to this trimmer cap. The lug with red wires was brushing up against the grounded shield.
With that fixed, I was able to power the set up but only silence on the BC band and weird howling on SW. I checked the 6A7 with a scope and found odd waveforms. Maybe the oscillator coil is bad after all![Icon_confused Icon_confused](https://philcoradio.com/phorum/images/smilies/icon_confused.gif)
