Hello all,

This is my first post, so please be kind.

My Grandpa was an avid Ham and Shortwave Radio enthusiast. After he passed,
I found a box full of old tubes in his garage. I would like to gain some
knowledge about the applications of the various tubes, and ultimately find
out if they would have any value to a collecter. Below is a complete list,
along with what cross reference numbers I have been able to locate, so far.
Any help with THAT is also much appreciated!

Vintage Vacuum Tubes:

Hi Allan:

I remember using all but a couple or so. They were very common and found
service in radio and TV. There are a handful of types that go back to the
40's. I'll stick my neck out and say that the type 41 is the oldest of the
bunch. I don't see any tube types that I recognize as collectable and I
don't think there is one that can't be bought at a tube dealer at modest
cost. For the most part, the assortment of tubes that you have were the
types that most of us would have in a well stocked parts drawer for
replacements.

However... if you had a case of brand new 12AX7's you would be in BIG BUCKS
with some variants!!!
See http://www.audiotubes.com/12ax7.htm#12ax7 list

As far as asking for applications... like another poster suggested, get an
old RCA receiving tube manual. The old ARRL Handbooks had a nice reference
on receiving and transmitting tubes in the back---probably a Handbook from
the 1960's would do fine for you. A web search might help on finding the
particulars of some of those types too.
