Finally completed my Zenith tube Transoceanic collection

[Jeffhs]

I have one post-war solid-state Zenith TO in good shape and works well on all bands, except the AM band is dead; probably an open circuit in the oscillator coil (I think the radio was made in '65 or at least some time in the late sixties, owing to the lack of Conelrad symbols on the AM radio dial). The rest of my Zenith radios are post war as well. I also have another post-war TO which is in worse shape yet; that is, it probably plays, but there are the proverbial million things wrong with it, which is why I haven't done much with it yet. I have a Zenith K731 AM-FM table radio which works quite well, and a C845 (its picture is my avatar) which works so well it can probably run rings around any modern set.

It's unusual that the AM band doesn't work, but the higher frequency bands do! I would check and clean the band selector switch first before delving into the oscillator circuitry. Comes from experience!
