I have had poor luck with "new" Eastern European
5814A's/12AU7's/ECC82's. They amplify but but interelement shorts and
leaks are problematic.

I have had very good luck buying used and new 5814A's on E-bay.
Used-tested-good 5-star tubes go for a dollar or two each. Occasionally
moderately large lots (more than 100 at a time) of new JAN Philips tubes
with date codes in the mid-80's show up, and they sell for $2-$3 a piece
in that quantity (I think the last lot got sold to a guy with "r390" in
his ID!). Onesies-twosies these sell for $5.70 at AES (contrast that
with $12-$17 prices for tubes numbered "12AU7A".)
