Latest attempt at a tunnel diode flipflop with two tunnel diodes driving each other.
The idea is when one diode oscillates the coil will have one end in opposite phase to the other so that the other diode will flip opposite. The coil is between diodes and other coils are chokes going to a central choke in the feed line. Every thing in very small and at this stage frequency does not matter - just get it going and hope it quantum switches.
If it quantum switches the rise and fall times should be very fast - f/sec ??
