RE: Forget the technical summary.......( long )

Hey Jeff - In regards to speakers, I have at least one pair that are 100 db or more (15" University coaxials) so I should be OK. I don't usually listen that loudly anyway. My only previous DIY amp is a SE 45 so the PP 6B4G should have plenty of power compared to that.

Of course I will, no doubt, come to my own conclusions ultimately since I plan to experiment a bit with this amp. But it's nice to have some specific suggestions on things to try and I welcome all you guys' experience and knowledge regardless of whether it's based on "by the book" technical theory or purely on listening.

I am trying some of your ideas with the PS. I'm using a single Signal power transformer and separate rectifiers and LCLC sections (one Triad C-40X and one Stancor C-2708 in each) for the outputs and inputs.

One variation is that I'm using hybrid rectifiers for the B+ sections. UF4007s on the negative side with snubbers and 5AR4 on the positive side. I know you dislike the 5AR4 but I like the idea of a gentler start up. I'm sure I'll try 5U4s too, since I have some of those. Of course I'd have to use different power transformer taps to adjust the B+ higher since the 5U4 will drop considerably more voltage. Some of your other rectifier suggestions like the 5V4G and 5V3 would require even more changes.
