Thanks ,but surprisingly hard to find out.I've no idea. You would probably find out in a google search. They will last for many years though, it's the output valves that wear quickest.

Original GEC KT88s, or original Gold Lion KT88s, or original General Electric (GE) or Tung-Sol 6550s. Anything other will not be reliable...
