Does anyone have a schematic for this "half-state" radio?
7/1/2014 10:43:13 PMEdd






Sir Mark. . . . .





I'm not having that units schematic to reference . . . . just yet.


"Half state" . . . . with that probably being all tube up to the AF output stage where, in early days, they used a


high voltage npn transistor, that further feeds into an output transformer . . .right ?




Will pick up and scan for you after my next trip out to the ole'Mule Barn . . (Archives).


If any devious parts are already being detected / suspicioned, describe them, and I will research and include

them within the prepped schematic.







73's de Edd







The statistics on sanity is that one out of every four persons is suffering from SOME sort of mental illness.


Then just think of your three best friends — if they’re okay, then it’s you.

Sir Mark. . . . .





The schematic now reveals your "half state" as being the other extreme end from which I had expected, specifically, with its FM front end of the unit, being the portion which is solidly stated.






73's de Edd







A transistor protected by a slow-blo fuse will protect the fuse by blowing its emitter link open first.

Thanks Edd! I have the schematic.
