|Hiatt Collins||Re: Tube voltage limits and tube regulators|
I could, and it probably would be simpler. I've never built an amp with a tube pass regulator, so I thought I'd give it a whirl with this one.
I know that you can put the gas regulators in series to get a higher voltage drop, but I didn't know that you could parallel them for more current handling. Do you have to use resistors to isolate them? It's my understanding that you can't parallel zeners without some sort of resistors, and I think of these gas discharge tubes as being the tube equivalent of a zener.
Back to the regulator - If I used the 0A2 or similar, I'd probably put them in series with the screen supply to drop, say, 250-300V, rather than build a shunt regulator. I'm more concerned about keeping the screen voltage for the 6AU5/6AV5 around its limits rather than really regulating the voltage as such.
