 		A 7 segment display which has nothing but segments. I have a few of these.

If you look closely you can see the LED die under the middle segment.

Jennings vacuum variable capacitors.

1293460803 30 FT98422 Reverbtank1
Spring reverb tank.

1293460803 30 FT98422 Celem1
Capacitor from an induction heater. An industrial heater would use this as an extra tuning cap, but I found it could melt a steel bolt by itself.

Bird dual wattmeter, with 1kW and 5kW low frequency slugs.

 		I need to find one of those heavy duty caps.

Here's a 3 lead capacitor. It's electrolytic but both sides are marked +, WTF?

1293465333 543 FT0 Hk 3c24 Hf Power Triode J


These rather masculine looking oddities are proof that size isn't always the important thing.

With 2kV on the anode, the Heintz & Kaufman 3C24 HF power triode has an unmodulated output power of 100W at frequencies up to 60MHz.

I found these in the attic in an old steamer trunk which didn't appear to have been opened for years.
