Re: Have old tubes, need INFO!

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!

Thanks so much, in advance, for your collective assistance!

Most of the numbers I recognize are radio tubes from the 40s or so.
Others on your list may also be familiar, but the numbers may be
unreadable.  A number like 5-30 might be a date code.  Something like
the 30th week of a "5" year such as 1945 or 1955.

As far as value, you can check the tube price list at:

Most tube vendors sell new tubes at a lower price.  Used tubes go for
even less.  Lots such as this are frequently sold on E-bay.  This is a
better than average lot.  Most of the ebay lots have a bunch of series
string TV tubes, which don't have much real value now.
