Need Dial string diagram f/ Audiotronics 250 tube radio
 

Hi,
I recently bought a commercial Audiotronics 250 AM/FM tube radio off of e(p)lay. Plays really well with one problem: dial string broken. If anyone can provide me with a dial stringing diagram for this model; I'd appreciate it. Any other general information that you could provide on this radio would be nice. One strange thing I noticed is that it uses a 6T9 compactron for the audio driver and output stage. This is the first radio I've ever seen with a compactron tube.

Thanks again for your help, Bryan
