Anyway, back to the question from LSJuan. From memory I got a "U" build kit - frequency generator - from an electronics shop (Altronics in Australia), and built it. USD$50. A microprocessor controller like a Teensy can also do it, "just" takes some C programming. And circuit design to drive the FF pin.
Trust that makes sense.
