As this thingy is diminishing and its getting harder to find, spotted at an old brick & mortar shop, guess they must be really old stock, grabbed the complete wattage series with 2 pieces at each value, all just 5 bucks.
When it comes to AC dummy load with pure power factor at 1 (pure one), and can shine too, compared to dumb power resistor, now I'm ready.

Nice catch.QuoteWhen it comes to AC dummy load with pure power factor at 1 (pure one), and can shine too, compared to dumb power resistor, now I'm ready.
and AC current limiter, too.

Careful with those, they do have a short life, and tend to fail short circuit briefly when they fail. I also have a lifetime supply, though in my case I chose ones made in the EU, so have a collection of Polish, Hungarian and even French and Netherlands made lamps, plus a good number of pre war German made Siemens lamps, in both frosted and clear forms, with tungsten and tantalum filaments.
With incandescent lamps recent ones are pretty much junk, never meeting the rated lifetime, and often failing within 100 hours. You cannot blame the manufacturers though, as often the machinery they are using is the old EU equipment, shipped over complete to the cheaper labour regions, and the lamp quality is as good, just that to compete on a cost basis they cut cost by reducing the most expensive item in the lamp, the actual tungsten filament length, so that the lamp runs hotter and brighter, but with a shorter life.
Finally the TL-22 leads for the DE-5000 arrived.
In order to make the polarity easily identifiable, used red and black heat shrink tube.
The + and - marking on the TL-22 would eventually be easy to miss.

Curious, what are you measuring with an LCR meter where polarity would matter?
Caps or diodes?
Xilinx Kintex UltraScale+ XCKU15P-FFVE1517-2-i FPGAs for $250 each on Ebay. List price $3500. Should be capable of 8x100G Ethernet.
Sold as salvageable components on Mellanox Innova-2 Flex MNV303212A-ADLT cards i.e. PCIe "accelerators" featuring the FPGA and a ConnectX-5 ASIC.
Hoping to desolder the FPGAs and rework them onto a custom PCB to use for development. Just one such board would save thousands of dollars - my rework station would have paid for itself!
