I will make amends. My purchase rate of TE is higher than ever  :-DD

I got rid of the 7L12 because quite frankly it scared me. It could literally turn into a brick at any moment with no hope of repair. There are literally no parts mules for it or anything.

And now for something completely different. A small 50 ohm load. 10KW. And yes, that's the coax connector on the front  :-DD

Ah, I'm glad someone took a photo of that. Not exactly an N/BNC/SMA connector, though.

yep 10kW into 50R is roughly 707V RMS, 1kV peak so minimum connector is a C type or HN.

So what did I bag?

The Mullard Transistor Circuits Manual ...

Damn that is nice bedtime lecture, I can see why it's highly sought after!

OK, so my haul was

* a Fluke 515a portable calibrator for £20. Quick check shows Vdc excellent, µVdc cockeyed, resistors good, Vac not bad, unlikely the NiCd battery works, missing the unique front panel switch which I'll probably have to "improvise"
* three Muirhead decade resistors for £5. Looks good.
* Cropico 4 decade resistor box. A few resistors o/c, but can be replaced
* and the thing below for £5, which is probably as near as I will get to having a slice of the one lying around in my first job
