Well, Wayne, I'm scared to be seen on that picture by all forum members :-), so here are prices for Svetlana 300B. The tubes 2A3 are not available right now.I can get Svetlana 300B tubes for $95 (new), or matched pairs for $160 (matched within +/-3mA), $150 (matched within +/- 5mA) or $140 (+/- 10mA).
Tubes was made after November 2000.
You also have to pay shipping from Odessa, Ukraine.
The tubes SV300B SE will be available in the end of April. Soon I'll let you know all necessary info about them.

I'll gladly answer any your question.
