Default 500K pot for Bosch 28

Also, this pot is a wirewound, which does not seem right considering
it's across a tuned circuit in the first stage. It seems that it would
change the inductance in the circuit.


The point in the circuit it's in - it doesn't matter - as it's intended
to "shunt" signal anyway (as you noted - it's the volume control - and
it does it's job pretty well).

What is the voltage drop on this pot? You may be able to use a 1 watt
carbon pot instead of the ww as 500K is not very common.


Ain't none to speak of - the pot is antenna to ground - with the wiper
"picking off" signal to the grid of the 1st RF -- and obvisouly
providing ground return for the grid. So yes, a carbon 500K would
probably work - but - an original would be nicer.

Brenda- remember - the Eveready (National Carbon) models 1, 2, 3, 20 &
21 are the same chassis - so would have that pot as well... just another
place to look.
