Newproduction power tubes: Reliablity


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.

"As if we needed any more reasons to side with Russia over China."

For many people being married to a Russian is not a reason enough to pick Russian tubes over Chinese.

I've used KT150s for the past couple of years without issue.KT88s have been GL and JJ,no issues.
Slovak Republic.

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
is there a question in your post?

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. 

e GL KT88,

Tried em, didn't like them, return to vivatubes
Much prefer the Svet new 6550's, the new plant uses the exact same equipemnt as the burned down plant, 

NOS Svet 6550 = New Production Svet 6550, exact same tube,
