I have been wanting to do more audio projects for you all but I am not sure what to build. You know I like to build big amplifiers and I don't know where I would put it afterwards. 🙂 Thank you for thinking of me.
Good question. For open distance, I would like to give it an inch or so. As for resistors, your question prompted me to measure the 10KV rated resistors and they are 2 9/16 inches long. The two watt resistors I used are 5/8" long so five would be 3 1/8 inches. I have to admit, I did not do that math before you asked the question. I do not know if that is truly a voltage equivalent but it has always worked, plus in this case the end resistor goes into a 2.5M pot to cal the reading. I should put back-to-back diodes across the meter also as I always do in my transmitter meters. That can definitely save the meter in a tube short. I put the sting of resistors in shrink tubing. The comment I made about not using a single resistor was learned the hard way years ago. It immediately arced and vaporized the inside of the meter turning it black around the movement area and it was only about 3 KV. Really makes a fellow feal dumb when something like that happens. 🙂

been missing your videos hope all is well. Excellent material on how to wire HV meter w/ calibration. Wish I had this vid a decade or so ago.

Live your videos! I for one would love some more el paso goodness
I love panel meters too. I picked up some really nice ones at the HAM swap meet.
The vintage Triplett and Simpson are very good but my favorite has always been Weston. 73
I really love panel meters too. 73!

I did.
Thanks for sharing. 🍻👍
Thanks for the info!
Glad you didn’t blow it to smithereens ;-) How much gap do you need at 10kV? EJP

@ElPasoTubeAmps I guess you put the pot at the LV end of the string?
