What is the best tube for a Conrad Johnson

Hello

I have an older Conrad johnson permier 4 power amp in exellent condition running the top end of a set of infility RS-1b's. They have 7 emims and 4 emits per side. They are ribbon drivers. I want to retube it and would like an idea what EL34 power tube would sound nicer on my speakers. One other question is how do ruby tubes sound.

Thanks
Darin

I have a pair of NOS EL34 teles. the rare(r) type with the small wings on each plate. Feel free to email if interested. $100/ea is a steal for real NOS West german teles. (not RFT, etc.), and these will be more than that. Factory matched pair w/orig boxes btw.

Your best bet is update the 5751 and 6Cg7 tubes first - those will have more effect than EL34s. I had a pair of CJ Pr. 5s for a while, and found the (old) Svetlana EL34 to be the best that was reasonably affordable. I still have some nice 5751s and 6CG7s to part with that are left over from those days if anyone is in the market...
