Chris' Old Radios

As found June 2000 awaiting it's turn on the bench
This radio is finished and awaiting me to take new pictures. The electronics required little work, capacitors all around, 2 39/44s and a 36 to replace 24As that someone had attempted to use.
The missing shadow meter posed the biggest challenge.
Found a used unit but no lens, wired it back into the circuit
and nothing, after a day or two poking around I
discovered someone had directly wired the AVC bus to
ground!  Not good especially if you want a shadow meter
to work properly. The lens was replaced with a small
piece of dial material donated by a fellow collector.
The material is  available from AES.

Shadow Meter

Shadow meter works much like a tuning eye tube.
A iron vain inside the meter assembly rotates
with signal strength and changes the light cast
upon the shadow screen. A strong signal is
viewed as a thin dark line in the middle of the
lit screen, weak signal is a wider line creating a
open and closed effect like it's tube cousin.

Short a pair of original filter cans removed
many years ago and a tube shield
but it still looks nice.
