Here, more or less always the same result.

Feel free to post something if you wish, I have no much time for now.

I think it could be a kind sort of special Infrared heater, ie, a resistance in a quartz tube, maybe, or something similar. And concerning to the coating of which you speak, well, do not think is the classic gold coating, as this is thicker, or it seems to me, but maybe something new and...

Ok, but if someone wants to put an object, go ahead, I have no time for do this now :yh:

For the amount that I disassembled in my life and the shape of this, and the connections that have this device, I would say that is maybe a kind of old Magnetron, perhaps a cavity Magnetron.

No problema BS, everyone can propose whatever he wants :beer: I just wanted to clarify what is, and how this device works because I know a little this type of seals, that's all, and, no, I don't consider have won only for writing this clarification, so if someone wants to put something go...

Yes, they are 2 separate machines, but to make the game easier I've put the full set. Is not a morse code competition device. Clue: but as you all can have seen on the left side, it does have to do with the Morse code. No voicemail, telegraph mail, etc, or related to Fireworks.

No problem, here you go. Edit: Since there is no proposal yet, and it's late here, I go to sleep. If someone wants to put something else, go ahead.

Haha, yes, The gadgets and other attracted me to this page :p come on Peter, you don't need search for anything when you know the answers, please. To say that they were also used in Pal televisions (system used in many places in Europe) to delay the chrominance signal in 64 microseconds.
