How do they compare???
Is there a significant difference in headroom between them? I have a older pair of Mesa 6CA7s' that I am thinking about popping into my JCM800 2204 for shits and giggles. Just curious of you-alls experience.
I am very familiar with EL34s' and 6550s' in the amp. Just not the other two options. It currently has a pair of JJ El34s' in it now. The 6550s' were burly. Lots' of clean headroom. Had to be LOUD to get the amp to crunch. The '34s, not so much.
Thanks.
EL34/6CA7/KT77???
