However, I don't understand and don't share your "anti-feedback" religion. ;-)
when it comes to global negative feedback, i am agnostic,
if you can get away with none, why not?
but if you need it why not use it?
i have done it both ways and it is a case by case basis....
no one size fits all kinda thing...
6550 pp amp, G2 regulated supply....
Looks like you make a lot of tube amps.
I would like to share with you it's my latest project.
I know that it is very similar to McIntosh and I like it.

KIVIN,
congratulations for the new "Mc*ntosh GU 50 " Amp.
Perfect design Nice work.

yes, i have 3800 pcs. of tubes to play around with...
plus, i can make my own irons to any size and shape i want, not depending of manufactured ones....

Excellent build. Very pro.
It's VERY similar, a coincidence I guess.I would like to share with you it's my latest project.

By the way, looking at the tube list, I guess the design looks a bit like Priboi, but just to be sure, have you got a schematic to share?
This is my take on the Alex Gendrano design
DIY Single-Ended (SE) KT88 / 6L6 / EL34 / 6CA7 Tube Amplifier
they are 6L6GC tubes in the picture but I've since switched to EL34.

blue blue i like blue.....
another 6550 build in the works....
uses the 6J9 input tube and 6CM7 ltp splitters
and direct coupled cathode follower drives...
this is a class AB2 design....
regulated G2 and G1 bias supplies....
power traffo, OPT and chokes designed and built by yours truly...

Ta240, I have built four or five of them. So easy and works well. Nice blue glow on the tubes.
That's what appealed to me with the design, it is really a simple setup that even with being my first build I was able to understand the basics of what was happening throughout.
The online help coupled with a Dad that learned tube electronics from the Navy got me through the questions I did run into.
The blue glow had me worried at first, I hadn't seen tubes do that before.
The problem is I really want to build more but there are only so many amps a person can use

Someday those words in that order will make more sense to me. For now, much of that design is over my head.
Thanks!
On photo is when case was in progress, glass face panel.
and for those who wanted to see the schematic. (anode voltage 560-570V 50mA per each GU-50)
Also my amps have remote control

I need friends or relatives that are into audio more, then I'd have homes for more of them. I just finished an Amp Camp Amp and am (hopefully) putting a TDA7297 into a vintage oil can to give to my Dad for his garage.
The itch though is to build another tube amp.
Half of the battle there is breaking through the idea that so many have locked in their minds that 100 watts per channel is a must. I gave a cheap TDA7297 that I upgraded the capacitors on to a co-worker and he was so worried that 15 watts wouldn't be enough in his apartment. It was an ongoing conversation for the time I was waiting for it to arrive from China about 'How can I get more watts out of it?'. Every day 'what can we change to make it more powerful?' Finally when he used it he came in and said '15 watts is more than enough'.
