Re: 'Toll free' gets blasted with 6 kv !
Toll, That tops all my "got across HV" stories, and I have a few.? Unlike yours, all of mine were directly related to utter ignorance or criminal carelessness.? We can all learn from your experience -- don't use those Millen HF connectors.?? I would suggest -- get a ball-peen hammer with a wooden handle, and deliver a nice swift tap to every Millen HF connector you see. Or -- if you're a license queen -- remove them and sell them to CBers. 73 Jim N6OTQ PS -- "6 kV Man" indeed! |

Re: 'Toll free' gets blasted with 6 kv !
Bloody hell, Shane.? You are indeed lucky to be alive.? So someone traded an amp with you that had electrocuted its last owner?? That was really nice of them.? I think I'd invite them to come and look at my new truck ... and then run the bastard over....several times just to finish the job. Can you post a link to the HV connectors you used, please?? I've always hated those Millen connectors and in the past used some military surplus HV connectors that were floating around the fleamarkets 20 years ago, but I've run out of them and I don't know what they're called.? I need something that will handle about 7kV at a couple of amps. Thanks .... and stay lucky 73 Dave G0OIL

Re: 'Toll free' gets blasted with 6 kv !
¿ªÔÆÌåÓýI have tested a bunch of PL259 and depending on your luck they
run about 4-5KV before arcing.? More or less the same regardless
of the maker (the amphonels were not much better than the
el-cheapos).? 213 tests high as you say but can't recall what it
is.? My hipot runs to 15KV and that's not enough. 73/jeff/ac0c alpha-charlie-zero-charlie On 30-Dec-18 12:46 PM,

¿ªÔÆÌåÓýBest wishes to Shane & his family for a speedy recovery. One of the *worst* reactions from the old hens here was when I
said to always keep one hand in your pocket when dealing with
HV.... Which was immediately followed by people that had real-world experience almost being turned into toast by not following that basic rule... FFS, I've got nothing to prove here, not *here* amogst y'all...
although nobody from the hereafter that had a hand on the chassis
when he croaked has checked in to this *(unmoderated) list, and,
presumably, if AG6K was in Hell, he'd have QRMd it by now. Jim... having overthunk the choke thing... methinks that "if" you had 2H in the B+ AND 2H in the B-, THEN the back EMF would equalize.... and, and, well, Hell, what's the point of that? Where ya gonna put the scope leads, the meters... meh... it'd be easier to design a new class of (vacuum-tube) devices to clamp the V... Canadiodes... eh?
