Re: Series connected stabilizer valves: questions
Al, not sure whether this circuit is of any interest to you? It was originally posted/discussed on the Forum back in 2015 and I built it and was quite pleased with it. As mentioned earlier, I think I used 3 x 75V Zeners, but I'd need to check that to be sure and I cannot claim to have looked in any great detail at the tempco of the circuit. However, the use of the MOSFET eases the workload of the Zeners. Apart from the MOSFET (which needs a heatsink) it all went on to a piece of Veroboard and was quite compact.
