It is difficult to know what the best quality of valves to use in these repairs. I have gone with JJ 6L6s for the 5e3 and Tung Sols for the Bassman with an EH 12ax7 for the Goldentone.
Only time will tell whether these are the goods. Svetlana was one of my favorites and their new Winged C brand so far have been OK.
I will keep you posted.
