National SW-54 ISOLATED CHASSIS
#3

Gee I wonder how a 12BA7 would get a long in there instead of the 12BE6.
More gain and less noise.
Maybe was a ham that wanted to use it w/other stuff (transmitter) that was
@ earth ground. I would have bought an isolation transformer but I'm no
fun!
Get a load of those diodes! 1965 again.

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!
