Single Ended Triodes (SETs), the ultimate tube lovers dream.

RE: ALT. 1.

Thanks for responding. There is hardly any meaningful difference in dynamic impedances and ripple between the two supplies, Chris gave the impedance figures, ( 570 Ohms stock, 650 Ohms ALT.1, a 17% increase ) and I have originally posted, ALT 1. is 437 mVAC. versus 457 mVAC ripple with the original 10 HY choke, ( about a 5% decrease with ALT.1 ).

However, there IS a 14 times reduction in B+ filter series resistances with ALT.1 to the Finals tube. Which B+ filter would sound better ? Why?
