I have the CJ5 monos. 8 per mono. The beauty of "our" amps is the amp trim pots do the work.--No matching necessary. I use the Seimens,what brand are in there now?-What brand are you looking at?
tube matching in groups or bias
I have a pair of tube monoblocs that take ten el34's for each amp. Each tube can be biased individually. I will soon be to the point that the power tubes need to be replaced. In this situation is buying matched sets of tubes important or will any new el34 tube within the same brand work buy simply adjusting the bias? These tubes are generally cheaper if the matching process is not required, and matching twenty tubes could be quite an expensive process.
