square wave generator with tube

square wave generator

I'm trying to design a square wave generator with a tube. I tried transposing a solid state 741 design to the tube because the voltages are similar (plus or minus 15 volts for each amp).

It didn't work out and I got only clean output from the tube design. Any ideas?

Thanks, Leon

Re: square wave generator

I'm trying to design a square wave generator with a tube.

A cross coupled multivibrator is the standard circuit for it. You need two tubes or transistors to build it.

Ok thanks for the tip. I'm gonna try to look up some schematics, in the meantime, do you have any tips on schematics?

Thanks
