[Boatanchors] National SW-3 screen resistor

[Al Klase]

Hi Bob,

Now you've got me going.  This set has 237 stamped on the 
audio tube socket, and 5-pin unlabled ceramic sockets ('36) 
in the other two positions.  The power cable is a 
5-conductor affair with a separate lead for the screens.

B+ is controlled by a long-shafted rotary switch mounted 
vertically on the chassis just in front of the antenna and 
ground terminals.  You need to lift the lid to get to it. 
All looks original.

Al
