HI anyone.
I'm trying to develope a flip flop like switching on my tube amp (mesa mark III), cause i want to switch two leds to see my status channel, so i'd want to have a led off and the other one on, and viceversa when changing channel.
I've stated that the right circuit should be a monostable circuit or a flip flop one, but there's only a problem i can't solve.
This kind of circuit use momentary switch (latching or some kind else), but in a tube amp for to switch channel there is a temporary switch with two different states , ON/OFF.
Anyone knows how to mod the original flip flop circuit to let it works too with this kind of switch?

A flip-flop is not the right circuit if you're using a latching switch.

All you need really is one LED powered directly from the control voltage, and one inverter to drive the other LED from the inverted control voltage.

I would like to know how to make a flipflop from tubes. Would be cool to make a tube sub octaver.
