From what I have read, JJ tubes aren't the greatest. On the other hand, Electro-Harmonix and the new Tung-Sol (Russian made) tubes seem to receive positive reviews from folks.
You probably can't beat NOS USA tubes in any event, but NOS USA audiophool tubes such as 12AX7, 12AT7, and just about any hi-fi/stereo audio output tubes made in the USA command premium prices these days.
I would expect Yugoslav tubes to be lacking in quality. Remember the Yugo?
Nothing wrong with Westinghouse. If anything, you're ahead of the game there.
My 500-B has a mix of two JJ 7591 and two Electro-Harmonix 7591 tubes. Oned I get around to restoring that receiver, I'll probably bite the bullet and replace all four 7591s with a matched quad of EH tubes. They're a bit cheaper than the Tung-Sol reissues, but have a better reputation than JJ.
