Emerson 25A restoration
#11

The specs for the choke aren't very critical. Physical size is one of the more important so it can be fitted to the chassis. The more inductance the better. Current wise 20ma or higher should be fine. If you have a spare tube type output transformer that fits you can use the primary as a choke and leave the secondary unused. Or shoot Gary a note w/the dimensions and he could scare up something suitable. Or you could replace it w/resistor (abt 1-2K 2w) and increase the value of the two filter caps to 47mfd@160vdc.

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!
