Cathode bias question

[bungalowbill]

I have played Boogies for years and I just retubed them with matched sets as recommended in their manuals. I now have a cathode biased Crate V-32 with 4 el84 power tubes.....Do I need to replace them with a matched quartet or will the amp self bias? Thanks.....Joe

Yep a matched quad of JJ EL84 will sound great in that amp.
