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.
