Have for sale the following items,
Gen 0 night vision tube, seems intact and did power up about a year ago
4* IV12 bargraph tubes 2* "icecube" tubes Assorted high power LEDs, mostly green, some lenses, one 20W white on heatsink but have one red phlatlight left if I can find it.
3* copper peltiers, maybe OK but thermal glued together. Top one slightly scuffed but the stack does still cool OK. Flat CRT, including base Box of assorted valves including some suitable for VTTC (3 power triodes) Box of assorted bricks, not sure what power but includes some thyristors.
Also have a few random laptop screens including a 640*480 10.1" with driver PCB from digital picture frame and a monochrome panel originally from a 486 laptop These need backlights however. Some assorted panels which are non standard but may be OK if you can get a datasheet.
Test equipment: (heavy)2.4GHz frequency counter with batteries 2* non working scopes, the smaller one has bad tube but sort of works. Larger scope is 2 channel but needs recapping, and calibration.
Peak Atlas CA PCB only and non working RS IDM65 meter, maybe repairable but haven't the time to fix it and has missing parts. The CA powers up but drains batteries quickly...
Assorted EL wire (red, green, chasing) and small panel, will include HV5523 and 2* HV850
Random goodies box including transmitter PCBs, PIR sensors, 2.4GHz TX/RX video.
I also have a box of 8 assorted CCFL tubes and drivers of various colours, maybe suitable for lighting projects etc.
Have not listed on ebay yet, thought I'd ask on here first.
PM me if interested.. Please be aware I am not in the UK, heavy items may cost a lot to post.
