I've been using JJ KT-88's in my Quicksilver V4 Amps (4 per channel) with no problems. No biasing issues as well. Sounds great.
What about JJ KT88 tubes?
Whenever I read about KT88 tubes, I see EH, Gld Lion Reissue, Shuguang, etc, but JJ never seems to be mentioned. How do they stack up compared to others? I ask because I have a JJ828 integrated amp that seems due for a retubing. It uses 2 quads of KT88s. It currently has JJ tubes, and I'm wondering if something else might be better. I would try Treasure/Psvane, but I like to see the inside of the tube. Gold Lion seems popular, but with reliability issues. How do JJ stack up against Shuguang or EH?
