WOW. and I thought the ones I have from the 50’s was old. I grabbed them from 3 old TV’s when I was a boy, before my great Aunt had them taken to the dump. I had no idea what they even were back then, I just thought she should keep them. I now own her old house, and found them when I moved in, along with the switches, coils, and every thing else I removed back then. Needless to say they will never be put on ebay, or anywhere else. My son will some day own them when he is older.

Absolutely beautiful old tubes and unique collectors items. I remember in 1967 (when I was 12 years old) I went to the Waterlooplein market in Amsterdam (when it still was a real flee market with all kinds of goods) I also saw such early tube types, for 1 guilder or so (half a dollar). I could not buy them then. They were rare old Philips types and looked like normal bulbs/glow lamps.

Hey Frank,
It is interest to see how fast electronics developed. Back in 1914-1919 this stuff was cutting edge technology. Thanks.

That ‘S’ may be the manufacture of the bakelite base, maybe? I’ll keep looking or maybe another YouTuber will know. We are looking back, close to the beginnings of all electronics. And tube audio amplifiers sound the best still today. Thanks.

It would be very interesting to know who the original owns were, to late to dust for prints. Thanks.

Like you said, where have those tubes been for the last 90 years… What roads have they gone down to find you In NC? No way to know… Fascinating. JC

It would be amazing to see one of those receivers. The key is a small pin on the side of the base of the tube. The tube sockets have a metal sleeves with a one vertical slot. The pin fit down the slot and then you turn the tube to lock it in. I have two videos on a 1925 Magnavox radio, I think you can see the tube sockets there. Thanks.

Thanks. I think these are the earliest vacuum tubes I have. I have friends who own earlier tubes like a Lee de Forest Audion. An amazing part of radio history.
