What audio tubes were found in two random tube caddies

Please see pictures. Large RCA caddie came with a radio collection from an estate where the person collected radios but had worked on TV,s for the local Zenith dealer. The Westinghouse caddie came from the CC-AWA show back in March. Box holds all the good tubes found in both caddies.DSCN1783.JPG DSCN1784.JPG DSCN1785.JPG DSCN1786.JPG DSCN1789.JPG Westinghouse caddie is from the early 1960,s but as you can tell most good audio types had been removed in the past.

many of the tube caddies were used by TV repair guys so mostly TV tubes were in them. But appears you found a few audio tubes in there.
 
On the third picture I see a 6BK5 (beam power tube), a 12C5 (beam power tube), and a 6BW4 (double rectifier). Although probably never used in commercial Hi-Fi products, they can be used for audio though (the 6BK5 and 12C5 for lowish power output), so maybe they deserve to be 'promoted' to the box on the fifth picture.
 
I saw a 6BN4 which I've used to drive a 300B. You've got a Dynaco MK3 so you know the 6AN8 is a good tube.
It's nice having the pin straighteners on the lid.
 
If you post close up pics of all the tubes that you left in both of the caddies there very well may be others that can be used for audio. The pic of the Westinghouse caddie is not detailed enough to see the numbers.

Lots of "TV tubes" that are overlooked can be used in audio. They're unfamiliar because they were not used in commercially sold audio gear but, if you're into DIY you don't have to limit your choices.
 
Thanks for all the comments. The RCA caddie was mostly all pulls. The other caddie had the better stuff. There were three RCA 6L6GC in caddie, another person watched me go thru the tubes and saw two of those as I looked at each one both were black plates. He asked how much, I told him double what you just saw me pay for the caddie. He paid.
 
6BW4 can sub for 6V4,(EZ80), also 6CA4 (EZ81) in some cases. One pin difference - add a jumper wire to the socket and either tube will work. Output current is less than 6CA4, but not every application needs 150 mA.
