Does two matched pairs make a quad el34


I got 4 extra tubes with an amp I purchased, never used black treasure 6ca7-z, the boxes say 28, 31, 58, 62 mA. I have a shindo montrachet and was curious if having divergent pairs on each side would cause any problems if everything is biased to spec? Would there there be an audible difference?

Then you are ok. It also seems to be an fixed bias type amp, ( The terms are counterintuitive fixed bias is adjustable, autobias is the type that you don't change, it changes itself, it requires fairly close matched tubes) which require relatively close matches before implementation.
You shouldn't hear a great difference between the channels.
What amp is it that you are using these tubes in?
Well as luck would have it my quad of NOS dynawatt el34 just arrived today so I will just get those in and go with those. Thanks for the insights. I might try them at some point.
