Finished stuffing caps and put the chassis back together. Note I did find a round aluminum cap that approximates the original that was in the chassis for the three electrolytic caps #23, 24 and 25. There is room and a lug for the #25 cap that is no longer in the set because of the modifications made for the permanent magnet speaker but if someone found an original speaker and field coil, it could go back to original (but that will have to be the next guy in line). It still looks like a pig!

I powered up with a dim bulb and there were no direct shorts so a full power up seemed to go ok although I had no sound until I started rotating the tuning cap. Then there was static and I could see some arcing around one of the mounting screws that connects the tuner housing to the chassis and is supposed to be electrically isolated from the chassis. The rubber grommet had failed and need replacing. After that I was able to get our one strong AM station although the sound was not great and there was some scratchyness to it. No sound at all on the short wave band but I only have a 10' wire antenna. Will have to check more and do some alignment. I will also attempt to clean up the chassis a bit more. All-in-all I'm pleased that its at least acting like a radio.

I've started toning the cabinet but ran out of good weather. More of those photos later.
