Get some old tube manuals -- such as the RCA and Sylvania pubs --- available on e-bay or Ham Swap Meets

Your library may have them.

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!


Best regards,
Alan Pollard
