This is the oldest device in my shack. It has about the same age with me. It is a signal generator made in fifties by TESTGEAR (ACTON) LTD, a small family business company. (You can find info about them following this link ). It came to me totally unexpectedly. It previously belonged to an Englishman ham who past away recently. A relative of him, who is a good friend of mine, she picked up from his shack and thought to bring it to me as a gift. I have not to say how much I appreciated this gesture. Thank you Moira. It was in a good cosmetic condition but I was curious if it was still working after all these years. So I unscrewed the back to see what it looked inside. With a great surprise I found out that the interior was still in excellent condition too. Shiny tubes and pretty capacitors! Take a look! What a construction? This is the pre-transistor era.
…And finally it is working properly as at the first day out of the box, still producing decent signals. Wow!
Now, there is a real question. What can you do with it when the modern transceivers have a stability of 0.05ppm? Practically nothing. Just admire….
