Did the 38-3 have an antenna?
#7

How does this radio perform? The reason I ask is there is a fairly nice one in an antique store (overpriced, of course - but LOCAL). I was curious what "magnetic tuning" was so I looked up the schematic (looks like it is just some sort of AFC, like in some high-end Zeniths).

But what was curious was that Philco would go to the trouble to implement AFC, and then use some sort of strange method of implementing push-pull audio by driving the grid of one push-pull tube from the screen of the other tube! How could that possibly work (well, at least). Surely adding a phase inverter tube would not cost that much. So I am curious as to how this radio sounds.

It was also not obvious in the antique store how this radio is tuned. There seemed to be some sort of crank arrancement.

Thanks
