I have probably about 400 radio & tv vacuum tubes. I bought many from a former tv/radio guy years ago, and they have been just collecting dust, so a neighbor said they are worth money. So I thought that maybe he is right & I should find people looking for them. Unfortunately I know longer own a tube checker. Many, probably most are in good condition & some are new as said on the boxes. Most are in Standard Tube boxes with the tube numbers on the box as well as the vacuum tube.
Now I have created a database to enter tube number, condition, manufacturer (I have from GE, Motorola, Curtis Mathis, Raytheon, Cornell, Delta...
Since some people on this forum collect or have antique radios, I thought maybe a good place to get some ideas for me to sell. I see that there are dealers that ask you to send them a list of what you have, so that is part of my reason to put them all in a database. (Some of my tubes I can't read the manufacturer, though I can usuall make out the tube # which usually agrees with the box.
I am wondering if I should advertise the ones I have online & then just let people contact me. Of course I have a handicap in not having a tube checker, I sold mine many years ago, a big mistake. I am finding many of my tubes are 2 to 5 dollars online with a few so far being 15 to 30 dollars. I haven't come across any real rare ones, but I have only entered 125 into the database. I am finding that I have many duplicates of common type tubes.
Here is one picture of the ones I entered this morning.
