So you need stability!

Then why you posted that hartley oscillator that's anything but stable ?

Don't understand these LRLs.... sometimes need stability... other times not... now you talk about tubes... then you wrote about fet amplifiers...

Also LRL related posts are affect by instability !?

Kind regards,
