| Hi
One of my activities requires the selection of well matched valves. I buy a batch of supposedly pre matched specimens and from 20 get about 8 or so useable ones for this application. Fortunately they can be used unmatched for far more positions so it is not a significant loss apart from the extra time running them up, testing, burning in and retesting.
If they really are 120 Bucks for a valve with limited application it would be almost insane to contemplate their usage.
