KT120 SE Tube Amplifier: Junk Tubes, now what?

Well some problems have arisen in use and it has nothing to do with the iron or the amp design, it's about the lack of QC on these Russian made power tubes. It seems like this has been an ongoing issue, and now given the war etc, it's just gotten worse. Here is an old thread on DIY audio highlighting the issues I have run into: https://www.diyaudio.com/community/th... I wish I had discovered these issues before I embarked on this project, this is super depressing. It's not like these amps are unusable, I now just don't believe it's possible to meet the design specs I designed these around. This series is a DIY project building a pair of single ended, ultralinear KT120 mono block style vacuum tube audio amplifiers. The goal is a pair of high power single ended amps, using only high quality parts, with as few things in the signal path as possible. This project is using output transformers from Thermionic Labs, custom made to use with KT120 output tubes, which you can buy here: https://www.thermioniclab.com/ They also should have power transformers and chokes for this project available.
