[Tondi007]

Thanks for this thread. I've inherited a number of antique radios and want to update a great sounding 42-1006 to include a aux jack. I've been fumbling around with the schematics and after a failed attempt to install the Radio Shack jack to the vol pot. (same jack you're using -- forgot the part number), I ran across this thread.

I am new to this but tried to identify where to break the circuit. Could someone confirm that I'm on the right path -- Or put me on the right one? One thing I'm confused about is were to but the ground. Also, there is a 3-pin jack on the back of the 42' model. Perhaps that would be easier to access.

I've posted the schematic below and marked my best guess where to break the circuit. The resolution is poor so it is also available here: http://www.nostalgiaair.org/PagesByModel...013486.pdf
