SET vs PSET

Jet and Charles,
I wanted to thank you for clearing up my split path comment, as I do have a push-pull amp and will be going SET. It sounds like with PSET the goal is to get both tubes of the parallel circuit to work exactly the same, because they are carrying the same signal. So, the increased power comes from the doubling of the same signal. Does that sound about right?

Hi Kenny,
You achieve double the power because you doubled the # of output tubes used. I believe a SET would be a fine match with your Hornings. Your speaker deserves a high quality SET that has premium quality output trandformers and very stout power supply built.Good luck.
Charles,

Hi Kenny,

Generally speaking, the PSET approach will get you more power, but, not the same amount of power that one would get by using the same kind of tube in a pushpull configuration.

Also, how much more power you would get with two output tubes vs. one is somewhat unclear. As Charles1dad has mentioned, there is the issue of the tubes not working identically. With my Audionote Kageki amps, I have noticed that after more than a year of operation, the two output tubes per channel will test quite differently, particularly for transconductance, when I test them on my Amplitrex tester. Whether this IS the result of the kind of imbalance issues that are claimed for PSET designs, or is attributable to something else, I have noticed this "problem." The amp will still sound great even when the tubes test very differently, but, with one tube being much weaker than the other output must be lower than before the tube started getting weak. I don't need much power, so that might account for why the amps still sound quite good. That the tubes in both amps would test so differently initially bothered me a bit, but, I "solved" that problem by no longer testing the tubes.

Thank you for the list and compare...very helpful .

"but, I "solved" that problem by no longer testing the tubes."

Love it !

I have always felt that 'if it ain't broke , don't fix it !

And thanks to Charles 1 dad also .

I will check out these suggestions and see what the availability and price looks like .

As I feared these things are out of my price range !
About the only thing that I could maybe afford would be a used Audion and the availability is not good .
Thank you to all who replied here . At least I learned something and that is always a good thing .

Happy Tunes .
