I thought the same abt 50yrs ago [Image: http://philcoradio.com/phorum/images/smi...n_evil.gif]  [Image: http://philcoradio.com/phorum/images/smi...on_lol.gif]

> one of the tubes was a 44, not a 36
Would replace the 39/44 w/ a 36. Both tubes do share the same base connection be the grid bias voltage is abt twice as much for the 39/44.

> it seems to like 450KC better than 460KC.
I see conflicting information on the IF frequency the US Philco seen to be 450kc and Canadian diagram states the IF as 460kc.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
