Philco 38-12 – 1937
I thought I’d talk for a minute about one of the radios that I’ve already sold. This 1937 Philco 38-12, as it arrived in the shop, had some major issues. The glass around the grid connection of the 6A7 tube had cracked, meaning that tube had to be replaced. In addition to the standard electronic restoration, an opened oscillator coil had to be diagnosed and rewound. The research I performed indicated that the wax used to seal these coils quite often had sulfur impurities, and in the presence of moisture caused the microfine coil winding to deteriorate to the point of being an open circuit. Now that these repairs have been made, this gear plays great and is very sensitive across the AM band. 5 tubes (AA5) 6A7 78 75 41 84. 11.5″ W x 8″ H x 6″ D @ 10lbs. Again, this radio has been sold and a big thanks to the owner for allowing me to photograph it in situ.
