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.
