According to my friend, one of the problems with tube reliability is that the production rooms where the vacuum is created in the envelope are not kept as stringently clean as they used to be. The Russians are making more reliable tubes than the Chinese, no doubt about it.
After I placed my tube order, an SVT came through my buddy's shop that had two of its six output tubes accidentally shot by trying to drive a cabinet with a dead short in it. I ended up with four nicely matched Sovteks (the bias didn't even need adjustment) for the price of a handshake. Feeling blessed to have a generous friend.
