Every time I suggest a basic tester, good/bad/strength/shorts
here comes 'it's got to be mutual ....'
the cheapest Hickok on hifishark is $599.
I suspect MOST people will NOT spend that (or more)
I had a big Hickock, my little Accurate 157 always found the same as the Hickock, I gave it away! I like my small portable, primarily to rule out bad or weak tubes or shorts when something goes wrong, for myself and friends, just to have the confidence the problem is more than likely not the tubes. And, to test the new ones I buy before I put them in place.
Without a basic tester, you keep yourself BLIND.

here's an accurate 151, working, $95. bucks, delivered
I've had the one my wife got me since 1983
For years people gave me used tubes, pulled from units being discarded, I have a heck of a lot of them, and most test good, they are great to use to keep listening while researching, picking, buying, waiting for a matched pair from someone other than Brent Jesse because sadly he closed.
