Some...ahem...specialist tried to do something to this radio long time ago. I can tell by soldering - wires smeared with solder, not reflowed. I am trying to change resistors and looking for them, so I could not understand how the heck the grid wire from the Green Eye tube goes to the same R3 pin the resistor R7 goes to. Considering I have to understand first which resistor is which.
Then I realzed he (i can safely assume it was he, those tome she woud not do this) simply connected it to the wrong place.
Good news, the XFMR seems to work, the secondary being about 700V (it is centertapped, so it will be half), the filament 6V, and the motor running. Have the dial light bulb bad, but I think the winding will be OK. (a separate winding for dial light).
....some people should not be allowed near the soldering iron.

| I'd try replacing the bulb first and if that doesn't do it, then change the 35Z5 and see if the problem goes away.NostalgiaRadioTime — 12:28 AM |
