Well... the transistors are okay in the two tone generator as are all of 
the other components I have tested.  I guess it must be operator error.  
It's not what you'd call a complicated piece of equipment.  Turn it on 
and set it for single or two tone and that's it.  Possibly it has been 
knocked out of adjustment because I have yet to get it to oscillate. 

So, does anyone by chance have a schematic or manual for the P&H 
Electronics Model TT-2B Two Tone Oscillator?  I said it was  Lafayette 
earlier, but I was looking at the city in which it was made, Lafayette, Ind.

Thanks for any help and/or advice.
Rick
