Hello All

[Johnny Kool]

Thanks for the concerns about high voltage circuits, i dooly apreciate
I really want to understand the fundamental of it all.
It will take quite a bit of time before i get to fly on my own and I will have to get winged by a fellow tech, i must agree.

I have to admit, i was a Refregeration Technician for 21 years. I delt with high voltage circuits(wiring) before, up to 630v on big roof top commercial panels, delt with electric motor start and run caps, relays, Ref.Compressor caps and windings and also a bit of home appliance 220v ie stoves, cloth dryers.
..in this trade i guess i was also electrician (but not lisence for residential or commercial housing), Welder, mig, arc, lead, solder (high pressure torch weld), pipe fitter, mechanical fitter, chemical gas handler, Plumber, A/C installer, i often cut holes in people house walls right thru the outside (fun lol), trouble shooter, problem solver
and cookie taster

Oh! I did get zapped on 120vac.. not a lot of fun , i also seen first hand my buddy get zapped on 240vac while grounded to a mfg ceiling crane! Freakie! (he's ok, i nicked named him "lucky"lol) got sting too on a small cap before lol

Never making that mistake again!

Following the "one hand behind your back" rule is the best advice I ever got, when dealing with tube, or any high voltage circuitry that can cause injury or death. I remember "you don't have to do it this way, but I'm a careless clod - so I do." I am too! and it's probably one of the reasons my heart still beats.

Worked around Radar's that used 100KVdc @ 3 Amps - the grounding rod looked like a short version (about 3 ft. - 1 meter long) of a knights lance. It would draw an arc from about 6 inches away and vibrate as the electrons ran through it to ground. Bigger rush than a double espresso!

The "one hand behind your back" rule is a good one - it saved my rear end many times. Also don't wear any jewelry - especially any necklace or dangling chains (always a problem for those fans of body piercing)

Hi JK - Sounds as if you have been around enough high voltage to have some decent respect for what it can do. Most of the tube powered stuff in audio usually runs in the 300 to 600 volt region - but you can find some stuff that will get up to 800 Vdc. If you have troubleshooting skills in electrical those are transportable to electronics so you are off to a good start!

Knocking holes in peoples walls will come in handy if you decide to install some IB (Infinite Baffle) sub woofers in the future!

got loads of respect for voltage

I don't have lots of equipement yet, i have a Fluke16 for tester and a bunch of hand tools etc.. guess a ocsillo, a power suppl, will be in order soon!

hi, i am also new in this forum sometimes the searching is bringing you to places that you do not expect.
i am from italy, and not really fanatic of sound and the stuff that are shown in this site but as a technician allways interested to the solutions and way to do things (we never stop learning).
also i have my own business that is directly involved with the music doing services for artists (not popular) to produce theyr own music and helping them for registering to the copyright office so when they will have the chance to be " famous " they can claim theyr own rights for the things that they did. is not only pleasure, guys it is also and substancially work.
