| Hi Edd, Unfortunately, the transformer will have to be replaced. In my effort to remove that thick tape... well, you can probably guess what happened. Mark : |

Every time I visit, I eat a whole package of Chocolate Oreo cookies while waiting in the lobby. : : :Sometimes . . . she has to cancel the rest of the afternoon's appointments ! : : : : :  : : : |

::This transistor radio has been an exercise in frustration.

::The most recent problem involved the driver transformer; an intermittent open was discovered. The normal primary DC resistance is shown on the schematic to be 650 Ohms; I measured 237 when there was a connection. There are two separate secondary windings; schematic lists 85 Ohms for each; I measured 35. The secondary does not have a center tap.

::The parts list shows only a Silvertone part number ( #45604-8). Can anyone recommend a replacement transformer? Thanks!
