What did you ruin today?

[N8ETQ]

   I always thought these things were good
for like a "Buzzillion" Volts.. apparently NOT.

What is it??  Looks to be a power resistor.

Ruined two MOSFETs and an IC. Possibly the test board they were on should be pitched. It does not have holes in it like the picture. I must work harder.

yes what is it in the picture??

[N8ETQ]

  Yes, it Was. 75k 100W. now it's garbage. 4Kv
on it. I had it sitting on a 10 mfd bathtub cap.
It punched through right where the edge of the
can was.

Old power resistors do not like humidity. I've seen nos ones do the Jacobs ladder across the entire winding.

All is not lost.
Strip it of wire and use it as a through the wall ceramic tube or as a standoff.
Use it as a mount for a wire glitch fuse. Leaving the terminals on it might be handy.
Clean it off and grind a wedge shaped hole in it near one end and make a whistle.
Launch bottle rockets from it.

I somehow managed to blow up my one digital camera when I went to charge it.

A 6J5 tube and it was my last one....Having trouble with a homebrew 160 meter VFO...the 6J5 was weak...Tested the VR 150 tube...OK..Looked in the Junk Box for another 6J5...Stuck it in the tube tester ...the filament voltage was on 50 from testing the VR tube...POP....Still looking for a 6J5

The one I have is very warbly when I tap it..and pissweak

Best to mount high voltage power resistors on ceramic stand-offs.  4KV across one resistor may be a bit much.  Better to use two resistors in series.

Last thing you would do is place one on other metal parts like you did.

We'll let you slide this time, but don't make that mistake again.  We may be forced to come to your QTH and remove all the tubes and fuses from your rigs.  In some extreme cases even tear up your license.

Yep, you get one chance before we report you to the "society for the prevention of cruelty to resistors" bunch .

Yep, and right out of the manual, "Care and feeding of power resistors," it states, "don't ship them loose in the mail.  Last one I got, loose in box, was broken cleanly in the middle. It clearly states in the manual that the higher the value, the finer the wire, and the less re-bar reinforcement you get for hoop strength.

You pipe people will appreciate that.  ...like wrapping your HV gun barrels with piano wire, heh, heh.

HV gun barrel? for a plasma rifle or what? Or is this a special tobacco pipe?

That instigates another possible use for the dead resistor - if the lugs are still there, wrap some heavy wire and make a high current shunt.
