I've heard similar design of these sort of multiple 6550 tubes... IMHO it's better to invest your money in a higher efficiency speaker and build a simple lower power amplifier be it SET or PP amp...

"I wonder how it would stack-up against Dogzilla?"

I don't think you can compare. Dogzilla was designed to be a guitar amp, and the Svetlana Six Pack wasn't. Still, why parallel up all those tubes instead of getting a pair of xmtr finals that could do the same job with a single pair? There are plenty of options for that.

Given that, who really needs that much power for home use. I have a project in the works that'll give 26WPC, and I don't believe I'll be going any higher. I'm not looking to fill a stadium with sound here.

I already have everything except the power transformers ,a few caps and the 6550's. I know most say it's a waste of money to build but i have bought some decent components for it. Riken and roederstein resistors . Jensen CFPO ,wima and Solen caps.Silver hookup wire ,cardas connectors.

One question i have, is it better to use the 9 1000uf 200v smaller caps in the PSU or 6 1500uf 450v caps. The 1500's are 3"diam x 5" tall and the 1000's are 1.5"diam x 1.25" tall.

For home theater i'm building 5-Aleph 2 clones.

Thanks
Glen

Further down the Svetlana technical bulletin page is an interesting piece on using a 6D22S as a rectifier.

Building an amp is expensive. Choosing a design is difficult as the end result can be an expensive mistake. I heard many so-so sounding tube amps and a few great amps. Once one hears a great amp, an average amp is basically unlistenable for any period of time.

Triode connected power tetrodes tubes sounds better than any pentode or tetrode per my experience. The best sounding true triode in my limited experience is the 45 tube. I prefer push-pull, but that slight almost chorus type sonics in the midrange of a SET has many followers. It boils down to what one is used to listening to that will form so many opinions on audio gear.

I find push-pull more dynamic & simply used to push-pull amp sonics. The best push-pull amp I used is either the PP 45 or PP 6V6GT triode connected. Both amps used same parts, simular audio transformers & power supply design. Both amps used higher quality parts.

To achieve the best sonics, the type of preamp & phase splitter tube will make or break an amp no matter how expensive the parts or using best quality power tubes. Even the rectifier tube has an impact on the sound.

Not being negative here. As for explaining my findings, 99% of readers will dismiss what I or others state anyways. So, put your question on top of my findings and you have basically little insight. I usually do not believe much of what I read & at times find someones opinion was right.

"Building an amp is expensive."

Tell me about it.

"Choosing a design is difficult as the end result can be an expensive mistake."

I certainly hope that is not the case with my project: I'd be pist aplenty. Still, I did my research and believe I've picked one fine final (807, class AB(1) ). From everything I could gather, 807s will work for what I listen to most of the time (Metal, Techno, other hard rock). Hopefully, others will agree.

Still, how bad could it possibly sound? I've been doing amps since the ninth grade, including one VT design that was all "wrong", according to the popular wisdom, and even that one sounded really good. Of course, I ripped out its guts for parts for the new amp.

"The best push-pull amp I used is either the PP 45 or PP 6V6GT triode connected."

Been hearing quite a bit from a wide variety of sources about 6V6s. That's definitely going to be my next project.
