[Boatanchors] An "Undocumented" BC-224 mods? Any sound familiar?

[Philip Atchley]

Hello,

I'm still working on this BC-224.  It's a bit of a headache, but I think 
I'm up to the task ;-)

Anyway, it's been more heavily "modded" than I first realized.  (Other 
than just the AC power supply where the dynamotor usually resides).

1.  The VT-152 output tube has been replaced with a VT-48 tube and the 
circuit modified with what is apparently a cathode resistor and bypass 
capacitor to ground. (I haven't determined the tube pinout of the VT48 
to be sure, but that's what it looks like)

2.  There is a variable resistor mounted inside the radio, adjacent to 
the "S" meter, not yet sure what it does, but the bracket certainly 
isn't original!

3.  A DPDT toggle switch  is mounted to the left, top side of the panel 
and the six wires are routed across the chassis and disappear under the 
added on power supply.  NOT at all sure what this switch is for.  The 
owner of the set doesn't know what this switch is for either and has 
said I may remove it if I wish. 

4.  There are also two "toggle switch sized holes" drilled in the upper 
right side of the radio, between the dial escutcheon and the Meter, but 
contain no controls.

Does any of the above mods sound familiar to anyone?
