The Sovtek 6H30Pi is commonly referred to as the "Supertube" by Balanced Audio Technology. Low plate resistance and high transconductance resulting with the gain being just slightly lower than that of the 6922. BAT has developed a proprietary circuit designed specifically for the 6H30P in order to realise its true dynamic and depth potential. Sometimes called the 6H30, 6N30 or 6N30P).
Cannot be used as a direct replacement for the 6922 or 6DJ8 tube!
