Thanks!

Any of the US, British and Japanese made in the 50's, 60's and 70's. They possibly have a longer life span than current production!
Hunting down a NOS, Mullard GZ34, from the Blackburn plant, would be well worth the time/effort/cost. Excellent sound qualities and may outlast the equipment, in which it’s installed.
