Years ago a my friend who build a SET for me on the 45 tube gave me a similar amp to trial, this time running a pair of NOS Marconi PX4 tubes....
Long story short, I never heard a better amp before or after driving my Khorns.... stunning. He wouldn't sell it to me as he had other plans for his Marconis. The amp was rewired for 6a3's which were not my thing.
Can anyone guide me to a kit / full build PX4 SET amp? Anyone here built one? I see KR make the PX4 tube now...
Thanks in advance.

Not aware of any kit for sale. But the design is simple enough, you could easily diy or get someone to build one for you.
Yes, couldn't you ask him for the circuit schematic? From there it wouldn't matter that much whether you had a kit or got someone to help you with your own build.
i think first tube is ef86 .
i.4 v bias and 1 ma for power tube like el86!!!!
px4 is expensive hifi tube . use good drivers like... b65 metal base ...ecc801s telefunken .....12ax7 tele.....valvo 6sl7.....brimar 13d2...and ...

I think EL86 is erratum.
