Compact ~20WPC Tube Amp

@atmasphere 

The funny thing is you could execute this with the same number of tube sections as used in a traditional SET right now (three total, including the power tube). The reason you don’t see this is the fact that you have to build a negative power supply. But if you did, you could build an SET that was inherently lower distortion which means it would be more transparent.

Interesting you say “more transparent “. ironic then, one of the first things I noticed when I heard my 300b SET mono blocks, superb transparency and startling nuance/inner detail. As if the speakers weren’t even in the room!

I do not possess the technical background or expertise  to explain why this is exactly  so. I can only rely on what I hear. That initial  listening encounter was striking!

I know they are mono blocks, but wow!  Ran these for years and they are wonderful and quite small.  Used would be about 4K.

+1 Will Vincent. Good value for money, and nice industrial design. His piece powers nicely a relatively insensitive set of Harbeths (albeit I’m not listening to rock @ 90 db). Even if I change tube amps, I will keep his, just to look at - it’s nice to own something made by an actual person in this day and age (if you go that route, I’d ask him to put an LED in the bias meter for cosmetic purposes). I have worked with Aric but he is next on my list

Good luck!

@charles1dad   The best amp I've ever heard uses 6sn7 to drive 6c33c.  I just picked up an amp to play with, partly because it uses 6sn7 to drive many choices of power tubes.  I'm eager to experiment with it.
