Philco 625B Assessment (UPDATE It works!)
#54

YES! It actually works! 
I powered it up for the first time today and it actually works pretty good! I have been fretting over the antenna transformer coil trying to get it hooked up properly. I also found a broken lead on the coil. Fixed that. I replaced all of the caps, many resistors, and some bad wiring. I removed all of the previous crappy repairs and strange modifications to the wiring, and brought everything back to the original schematic as designed.

I was nervous as could be, but I plugged it into my variac - dim bulb tester - isolation transformer and slowly added voltage. At about 100 volts the set came to life and then I heard static. I tuned in and found a local AM station and she played!

I do still have a good bit of work to finish. My volume pot has a burned spot on the track, so that will need t be replaced. I think my tubes are pretty weak and one the 78 tube has a loose base and cap. I have not done an alignment yet. So it is still a work in progress, but at least it didn't burn my shop to the ground... Icon_biggrin
