Vacuum Tube - 6CA7, JJ Electronics

Question:
I want to try these in a Bugera T50 Infinium. But,I can't seem to find any remarks on the web for this application. My T50 currently has a pair of the Bugera el34 tubes and I feel it compresses and begins to overdrive a little too soon. In the lead channel it reminds me the Hot Rod Deville "fizz." I'm looking for more headroom and dimension in my tone. I play mostly R&B styles and a touch of jazz fusion. Any advice is appreciated. Bob Herndon
