Zenith radio in 1936

I remembered that my 8th grade English teacher, Miss McGrath, would read aloud to us from the book: H*Y*M*A*N K*A*P*L*A*N.  So I did a little searching and found out that Leo Rosten (pen name: Leonard Q. Ross) started publishing the Kaplan stories in the New Yorker Magazine.

I fired up my copy of The Complete New Yorker and quickly found the Rosten stories:

  

In a way they are perfect as separate short stories since the 1930s were a different time with plenty of unfortunate stereotypes and language usage.  So a little taste goes a long way.

But I also saw this ad (the New Yorker used to be able to sell a LOT more ads than they do today):

Interesting in that this was a compact set made to run from 6 volts and probably included either an RF stage or an extra IF amp to boost the gain.  Plugging the price into the inflation calculator:

Wow, that is a LOT of money today and considering that the Depression was still an ongoing thing, yikes, I wonder how it sold ?  According to this page, less than 1000:

I looked at Beitmans radio diagrams but didn't see one quite like it.  Fortunately the Radio Museum had it:

Here is the schematic and it does have an RF amplifier:

  No rectifier tube needed with the built in vibrator supply ?  Not sure how that works - Zenith used to use special transformers in their TVs for regulation, maybe it's something similar ?  Overall a beauty but for that price it outta be !
