My wife recently brought home a Philco series 14 tube type radio from her grandmothers estate. We cleaned it up, plugged it in, and we had power. The problem is that two of the tubes are not lighting and we are therefore not able to get the radio to play. Where can I get these older tubes? There is what looks like grease pencil on the inside of the cabinet that reads 7-19-26 if that helps any.
Thanks for your help,
Jeff
