I'd like to hear the Shuguang Black Treasure KT88s, but I doubt I will drop that much coin to try them out.
I've read rave reviews of the Sophia blue 6SN7 but they are so expensive. So few dealers carry them too.

Good info, thanks!
What about for tube like the EL84, doesn't it require the 5y3gt for exactly these reasons? So that the tube is protected. I also thought the original 6L6 (not 6L6GC) also required a low voltage/current rectifier as they just aren't very robust output tubes. Am I wrong?
For 6L6 GC and above, I use a 5U4GB, and for KT88's and above I use the 5AR4.
