There is no shortage of tubes, boh new, and NOS.
Sovitek and Svetlana make copies of all common audio tubes. No guitar player uses solid
state equipment. Emic still rules the high power RF world, as there is not a
semiconductor substitution for a TV / Radio transmitter final output yet.
Antique Radio Supply is a great source for not only tubes, but tube design books and
materials.
You can find the Radiotron Designers Handbook, as well as all the RCA and GE books on the
web if you look a bit.

That's a pile of random loktals. What I'm talking about is a set of the
five tubes called for in an All-American-Five design. I might have to
rewire this thing for regular octals.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail? Slightly related is the subject of tubes in
radios. I get a kick out
of using tube radios. One big problem though is that there is no
source of brand-new tubes anymore. It's all new-old-stock. Tube-amp
enthusiasts have a ready supply of newly-manufactured tubes from a
small variety of eastern European makers, but those are almost
entirely unsuitable for making radios. I really wish some of these
makers could be convinced to make new signal tubes. I like my new-old
Philco, but the fact that it uses loktal tubes gives me an icky
feeling when using it. Nobody is selling AA5 loktal lineups on ebay.
They aren't? eBay item 180467734678 among others.
