I bought two bags of vacuum tubes at the Flea Market

Over 150 tubes for 40$, let's look at a few of them

Fantastic haul. The 6C33 is prized by builders of OTL amplifiers. It's a triode pass tube, very rugged as it was used in Russian fighter aircraft. I noticed an eye tube with the resistor across the base. These are in short supply, valued by restorers of vintage radios. It's a good job I don't have such a flea market near me, I would be unable to resist stocking up on these beautiful objects.

Nice Video & very Interesting Flea Market :-) The First Tube is called an "Accorn" type tube and has a dedicated Ceramic Ring Base, the exist as CCCP, US and European/British ones, I have quite a lot in my Collection :-).

I need dealers like the ones u got even if i go broke i will dish out some stupid over the top lamp amplifiers might end as bad financial decisions
Great video as always

That look like a bomb, high current diode tube.

The thyratron you said had a rating of 400 amps at 3.5kV is actually a hydrogen thyratron. The small cylinder inside near the base is a hydrogen generator, which is heated electrically to produce hydrogen by the decomposition of a small amount of titanium hydride in a reversible reaction. This is done in order to protect the elements in the tube from degradation by the hydrogen when the tube is not in operation.

The 6E5S is a near equivalent of the American 6E5 tube, the only significant difference being that the former uses an octal base.

Nice haul! I enjoy studying the structure and schematic of vacuum tubes or valves as you will. 🎈

7:40 unless it turned all white the tube is good, the white spots at the edges happen in most tubes after some long use or even from the factory when they seal the tube up.

I want to go to the flea markets you go to!!!

[LongnoseRob]

A follow up with datasheet info on the RF tubes would be interesting

4:13 this vacuum tube package type called "жёлудь" ("acorn")
7:10 It is high voltage kenotron (rated for 30 kV). Fun fact: during normal operation it emits around 10-100 milliroentgens per hour

[douro]

The ТХ2 (TKh2) is a thyratron, most likely a xenon type.

Flash lamps need a voltage of a few hundred volts at a very high current across the two large electrodes- typically supplied by a capacitor- and a trigger voltage of around 3-4kV.

Great flea-market "find!!" BTW, whoever taught you the pronunciation might need glasses; based on the correct spelling of "THYRATRON, " the pronunciation should be "thigh-ruh-tron, " and not your pronunciation, thrye-a-tron (the-rye-a-tron), the spelling for which would be "TH(A)RYATRON." Keep up the good work collecting as much nothing (true vacuum) as you can!!

PLUS, I didn't know the existence of that 6E5S, an octal-based version of the 6E5 "magic-eye" tube, which is a 6-pin base. I only knew of the octal 6AF6, dual eye, but without internal triode! Thank you!!

that is a lot of potential heating power. On a side note i wonder how comes you have such a perfect accent, are you american?

[winstonsmith]

What flea market had so many Warsaw Pact tubes?

[janno]

You cant believe how scared you make me while you are handeling vacuum tubes like scrap and just throwing them all over the place
