Yes, really nice work Vladimir.
Although it is more than 45 years ago that I studied Russian language,
(was a fanatic chess player at that time 😀 ),
still can read that Cyrillic Alphabet.
(But I do not know if you are from Russia, so if not please be not offended).

Thank you for your kind feedback. They are very useful to me. I read many useful articles on this forum, so I wanted to show my developments as just a hobby.
Here is a description of my KT77 PP amp:
And the schema:
I followed the schema but made some tweaks,as input tube I use the 12AY7 as it has lower gain than the ecc83 wich suits me.
And the phase shifter is now 12AT7 after consulting with a forum member.
And on top of the input tube I use this CCS:
And at the bottom of the phaseshifter I use this CCS:
The amp is now dead quiet.........
I should ad that it uses all JJ tubes.

The first commissioned MA-1 modular amplifier. Using triode connected 12 GE5 tubes, it's worth about 25W of sine wave drive. They wanted a blue power button instead of my usual red 😛
It features regulated bias, a safety relay that won't turn on B+ unless bias supply is working, and several "status" lights for unlikely troubleshooting.

Tube buffer with Tortuga ePotV.3 Mini (Remote not working as it should)
Buffer board is from Glassware Audio Design. Not sure whether I will build another with LDR volume controll. This is the second manufacturer I am having trouble with. I am still waiting for a board from a New Zealand guy (7 month and counting) I might just go with a quality pot in the future. A lot less hassle and the sound quality is really not better with an LDR volume controll.
I do love the Quality of the buffer board from Glassware however.

Looks great! Now this is vintage.
I chuckle when audiophiles talk about their vintage gear from 1998!

I chuckle when I realize Nirvana is now "Classic Rock"...
Or how about when you realize we're now closer to 2050 than 1990.
