I wound up buying five 10's -- two N.O.S. RCA VT-25's, a no-brander N.O.S. (allegedly) from a tube dealer, an Arcturus that tests super high for Gm on my Triplett 3444 and a bad "Aristocrat" (most likely rebranded; never heard of the name). Except for the no-brander, all came off eBay sites. There are, or were, a couple sellers peddling pairs of Sylvania VT-25's on eBay. Haven't checked lately as I am done buying 10's, so rest easy lovers of old radios and ham gear.
It turns out that data shown on <!-- w --><a class="postlink" href="http://www.nj7p.org/Tube.php">www.nj7p.org/Tube.php</a><!-- w --> for the 10Y was not entirely accurate. There was a printing error in an old tube manual showing 13 watts RMS output, where it should have been 1.3 watts -- same as the 10. The site continued this error.
Once again, this was a one-time deal. A trade for a Model 694 Canadian Stromberg-Carlson. There is nothing not to like about this 1947 table radio; nine tubes including push-pull 6L6's and a tuning eye, an 8" PM speaker and a hefty power transformer meant to operate on both 60 and 25-cycle current. No FM band, but there is an RCA phono jack on the rear apron of the chassis in which I plug my little Sony ST80W tuner so I can listen to FM (standard broadcast stations in my neck of the woods -- Wyoming -- have, without exception, wretched programming).
Thanks for everyone's input.
