Counterpoint tubes

[jazzer]

Owned SA-5000 and SA-220 since 1992. Replaced tubes in both in 2018. Yes, first time. I would appreciate thoughts on best tubes for these components. They drive a pair of Acoustat Model 3 slimline speakers with the Mk 121 transformer upgrade. Yes, about everything I have is from "back in the day."
Thanks in advance.

Jazzer: For Rectifier tubes in both the SA_5000 and SA-220 the best by far is the RFT EZ80 from Germany. They're about $20 each. I don't have any recommendations for the other tubes as my NP220 takes a different input tube than the 6DJ8/ 6992 tubes yours uses.

I agree. Also in my NP220 (now for sale actually) I tried other rectifiers: 6BW4 Sylvania and GE, EZ81 also but the best is without any doubt EZ80 RFT from Germany that is also very cheap in comparison with other tube NOS rectifiers...
my best
