The AK55C is once again playing and sounding pretty good. I used a couple of 2 watt resistors in parallel to create 4 watt resistors and hid them behind the existing wirewound fiber board, not perfect, but good enough. Replaced all but one of the old resistors using a molding technique to reproduce them (again not perfect but...) and got rid of the tacked in power resistors and electrolytic cap mess from a previous repair. Also had to take some of the rubber coated wires and re-sleeve them (actually easier than doing it in the '39-'42 Philcos).

Still some cosmetic work to do to clean up the chassis some more and repaint the tops of the large cans, then install it back into the table.
I was puzzled for awhile. Had all the right voltages on the tube plates, screens and grid caps but was not getting any stations. After rechecking all the coils I realized I had forgotten to reconnect the antenna coil to the tuning cap after having taking it out.... Bingo...talk radio started coming in loud and clear....
