The ARC version is different from BAT's
6H30-"Super Tube" or "Stuper Tube" ???
Ok.I see that many companies like Audio Research,BAT,Cary et la. are touting the 6H30 tube over 6922.What makes it different?What were the difficiencies of 6922?If it it is a better do you need a different circut design to use or can you swap?BAT VK5SE is touted as being a reasonably priced way to get this tube.Any others if it is indeed a holy grail?
