We have got some new valve technology coming and most of these are 21st century designs ( yes new technology) in audio valves !!! It is rare to see innovation in audio valve technology and JJ Electronics are doing it.

Over the weekend, I got my hands on a bunch of vintage audio valves and rectifiers. I went through all of them and tested them and that blew most of my weekend.
