Hello everybody

I know the Transitron only for Horizontal timebase applications in CRT circuits, to produce the saw tooth.

The last Transitron i have built, was based on a EF80 Tube in combination with a 5LO38I CRT.

The pourpose was to "show" the audio signal of a diy tube amp.

I searched a lot, but i never found any detailed information how to calculate a transitron correctly.

For instance, i dont see how to use this for a theremin?????

Playing around with electronics, i am interrested :)

I cannot simulate anything, i dont have spice, i am building and checking it out with meters and scopes.

this is a "terra incognita" for me too.

there is a nice  resource where a lot of Russian theremin related publications are processed by OCR. Thus,  you can easily use the google translator.
