Hello Bodger,

Thumbs up for what you achieve with the Lectron tubes !

I’m sure you will succeed in making the circuit stable.

A sine wave is always delicate. Too much amplification and it will distort.

Too little and will fade out.

I have experienced this too with the phase shift oscillator posted in this forum.

Man must tweak those circuits to have a stable sine output.

I’m sure you will find it !

Many greetings
