Request for opinions on Morgan Jones' 'statistical regulator'

45.88.190.181

Hello all,

Stumbled on this circuit in its "Valve Amplifiers" 4th ed., basically a (long) string of zeners fed by a CCS. Still trying to figure out the 'statistical' part though.

He claims very good performance and there are a couple positive reviews in posts here from members who built it dating back to 2015. Wondering if the design is still appreciated by more builders.

I'm still doubtful about the noise performance of the zener string... And say if I want to go up to 290V, I'm not sure if I dig soldering the 50+ 5.6V zeners. Using higher voltage zeners may just worsen the noise figure.

The circuit seems more geared towards input stages/low current signal stages, does anybody built it for an output stage, if at all pratical?

I'd try a simulation tomorrow to have some idea of line/load regulation.

Thanks for any information you can provide.

Let me know if interested.

I feel this is more of a curiosity than a practical solution. A LR8 three-terminal regulator driving one or more pass transistors is infinitely more versatile.

  Thanks TK for your reply and pointing at the LR8. Interesting part, I wasn't aware they made such high-voltage linear regs. An attractive alternative to a Maida circuit.
