[Boatanchors] GE YRS-1 Single Sideband Selector

[Chuck McGregor]

G'morning,

I've just applied my talent for finding boatanchors with unavailable 
documentation.  This morning's find is a General Electric  model YRS-1 
Single Sideband Selector.  Fifteen tubes, all octal except a 6C4 and 6AK5. 
The 6AK5 sits on a tiny chassis at the end of a cable, clearly intended 
to  sit inside a host receiver and buffer the IF output.  Front panel 
has  only a power switch and four pushbuttons, to select "Single 
Sideband-1", "Single Sideband-2", "Locked Oscillator",  or "Normal 
Reception".   It appears to be a commercial version of the  SSB adaptors 
often seen with R-380's and SP-600's.

Any information, or pointers toward a manual or schematic would be appreciated.

73,
