Take a look at this:

http://cgi.ebay.com/FAIRCHILD-AMPLIFIER-MODEL-620-2A3-300B-PP-EXCELLENT-/250722093940?pt=Vintage_Electronics_R2&hash=item3a60338b74

$57,000 for a pair of 10 watt (on a good day) audio amps full of original 
electrolytic caps and leaky Sprague black beauties.  And that is not the asking 
or buy it now price.  That is what someone PAID!!!!

Subject: [Amps] Matched Pairs of Tubes

I guess I just learned what makes a matched pair of tubes. A guy on fleabay has 
two
4-250A tubes advertised as a matched pair. The ad says that only the filaments 
have
been checked. I sent him/her an email asking how they were determined to be a
matched pair if only the filaments were checked. The reply was that they both 
had
the same date code, and that is what makes them a matched pair. Amazing. His/her
user name had the word audio in it.
