HP 5512A Electronic Counter 1969 Nixie test and teardown

Specifikation say 300kHz, this one count fine at 600kHz :-) capacitor replaced in the power supply, so that was easy to fix, 2 and 8 dont work in most left digit, it is the light sensitive resistor film board, not the counters or neon, all is explained in the video, #teardown #hewlettpackard #vintage -- I use auto generated subs, so if you find errors worth fixing, please comment with the time in the video you saw the error, i will be happy to fix it. This also apply to the Danish version. -- (Thanks to all my Sponsors / Traders / Swappers / Sellers / Buyers, without your support and constant flow of cool items in/out, none of this would be possible)
