Well, the EL34 is probably the best choice. More tubes to choose from.

Hey Marty can you PM me with a price on the FAT BOYS please? The Sylvania NOS 6CA7's are a little too precious to me for a standard JCM 800. I do like the extra glassy tone the 6CA7's have and a little scooped on the mids.
You know its a good question, I have tried a few of the different 6CA7's and they do sound big different then an EL34! But they are both true Power Pentodes and basically the same electrically, except the Max G2 voltage is 425vdc on the 6CA7 verses 500vdc on the EL34. But I have found some very old 6CA7's that pin1 & pin 8 were tied internally!
