@rdaily Now you have me all curious what TFM has to say on the topic. I presume some recalibrating.
@kentborg as well as how to not get killed from the high voltage...
@rdaily What is this close-up from?
@rdaily A linear amp, in which high voltage bleed resistors might have failed in an open state?
An aside: I admire that #HamRadio includes so many potentially dangerous, if not always lethal, activities.
Even Oliver Heaviside (who should be the #PatronSaint of hams and of real EEs) died of complications from falling off a ladder.
@rdaily What kit is that with the cheeky circuit board? I like it.
@zombiecube likely a high-powered HF vacuum tube amplifier with dangerous voltages which persist for several minutes even when unplugged.
@rdaily Ah, yes. I destroyed the tips on a pair of pliers when I was a kid “taking things apart”—accidentally learned with a powerful zap-pop-smoke how long capacitors hold a charge. Haven’t made that mistake again since.
@rdaily Excellent advice! 😁
