I bias my amps using a bias rite. There is not a lot of range on the bias control so you have to find tubes that are in the range.
Not a lot of range on Splawns on your Nitro? I honestly figured for quick testing that you would not bias but I'm glad you did. Makes the comparisons more valid obviously. Did you take note of the mismatches too when you first put in? I replied to your PM. Thanks.
I don't just throw tubes in an amp. If I try new tubes, I bias the amp accordingly. I put some SED KT88's in my Mako Mak2 Dorado yesterday. The bias was much higher for the 6550's that were in the amp so I had to lower it a lot to get it in the safe range for the new tubes. As far as Splawn's go, yeah, I know the range for the most part. I have read posts from guys who tried new tubes in their Splawn's and had to send them back for tubes with a higher rating so that they could get the bias set in the right range.
