Philco 89 2nd IF - dconant - 10-05-2026

Hello, Just thought I would mention I have restored a Philco 89 (123) where the 2nd IF transformer (the bell shaped one) had it's primary open resulting in no plate voltage on the 44 IF tube. I have done at least eight of these radios. Usually it is the antenna or oscillator coil that is open. So the 2nd IF is new to me. Did not find any loose wires. Had a parts chassis that donated it's coil. So on these radios from you know where something new cropped up. Also one of the 70K resistors was reading 160K. Quite the drift. Didn't look like it got hot. The power transformer had replaced. Mice got in there and made a nest and chewed some wires. The alignment was way off. Got lucky in that the antenna and osc coils were good. The speaker cone surround is pretty rotten so I used contact cement on it. All caps and most resistors have been replaced. Set plays well now.
