There isa topic going on concerning power tube issues in his PL amp, Some of us have power amps with 4-12 power tubes,, the higher number of the tubes in a amp means the more demand for reliability. The 2 countries making the most power tubes are china and russsia, So basically we can say this is a Russia vs China shootout.
China has come out with incredible numbers of power tubes, varieties and styles. These are the SET tubes. Russia has a far superior selection in the push pull category. IMHO , as i do have a push pull amp, I favor the russian labs as far as reliability. Here is where it counts, As we know, its no fun having a multiple power tube amp, and hearing 1 or more tubes going bad. A good tech is not cheap, nor so easy to locate. So in terms of reliability/push pull, I have to side with the russian labs. The one exception on russian power tube relaibility, is the russian KT150,, its a new tube and we have not yet had long term performance testing. It is not a tube I am the least bit interested in. .
I havea pair of JJ 6922's I refretfully won on ebay yesterday,, i will posta commebt, Maybe my prejudice will change,, but I really do not like EI/JJ czech/East EU tubes, generally speaking
No, Its a statement of belief,, = that china is not well know for relaible, musiacl sounding tubes, Sorry to say, when it comes to tubes (except in SET tubes) china Loses. I have Psvane 12AX7 in nice beautiful boxes, = lose to every EU NOS tube/every USA tube, Russian EH pre tubes are wonderful. vs china.
