What is needed to build a tube amp and what non?

What it should it not contain the tube amp? IMO, NFB that press the scene of the sound sending the part of signal back into the previouse stage. Unique amp must be built lineary without NFB, /in some causes linearity doesnt mean best sound/. IMO, never use tone control that change the sound. If You need more bass, use big bass speaker, if You need more high freeq. - use sensitivity tweeters, if You need meedle fr. - use sensitivity fullrange not less 8 inch. IMO, Hi End is back proportional to the number of composite parts - use simple decisions with not cheep parts- cheep parts - cheep sound!. Every passive part change the sound. IMO, in SE iron for OT must be 10-20 time more than output power, /for 5 W never use 5 W OT, but 50-100W/. IMO, in power supply use kenotrones, that provide soft start and soft amazing sound. Every time use iron chock and hmmm will be far from Your ears. IMO, do not use iron enclosure that collect noises....But your opinions?

The link works for me.

Azazello, I wish my second language skills were anywhere near as fluent as yours. I would like to apologize for any disparaging remarks by others here and applaud your interest in audio and undertaking such a project.

I can't speak to the circuit details your inquiring about. I have experienced unique strengths in many different amplifier designs and as of yet not one with even most of those strengths combined. I've enjoyed amplifiers with and without negative feedback. It must be their design execution that appeals to my ears.

Good luck with your project.

I listen posts about amps and I wondered, people very likes brand amps and ready to give thousnad money for amps, towers with ordinary components and speakers /Sorry for my bad English!/.....that are with common using, for ex. tube amps with cheep tubes, that are used in guitar amps, speakers that are used in thousand towers for common people. Audio listeners do not think there are audiomasters, that can make really HIEnd devices with quality better brands.....In CA I listened brand SE 300B for about 9000 $ and I noted nothing interesting, ordinary amps. The same with PP McIntosh, IMO, I wasnt wondered, dry sound.....And hundreds posts where people praises with dozens brands amps, towers. Expensive towers with 3 and more speakers are not very good choice, although that are built with expensive components. Deviding filters always press the sound and decrease it quality. Always better choice is direct coupled amp and speaker, really HiEnd.And I noted, people likes big power PP 50-100W  that is inexplicable, 3-5 W from SE with speakers with good semsitivity are enough for quality listening in big room. All above I dont understand....Sorry /encore une fois/, maybe Im in wrong place...

There was a guy (friend of Hornshopp?) who built, if I recall correctly, GM90 amp with switch mode power supplies which were very good sounding - extremely fast.
