The most common type of failure is dried up electrolytic capacitors.

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.
