[AMPS] Millen HV Connectors Factory Pricing

[K7RDX]

I really get my caps charged (he-he!) about all the bantering regarding the
Millen hv connectors. I`ve been using reds&whites in both of my 4pr1000a
amps for over 25 years with no problems at 5500vdc in one amp, 6700vdc in
the other! I think a lot of problems start with poor design & workmanship as
I`ve sure seen a lot of hashed together amps some people try to build!
Something I discovered several years ago: Belden # 734710 7mm metalic spark
plug wire,availiable at NAPA auto suppliers, great for hv amp wiring.
I really can`t figure why anyone would want to run shielding on any hv
wiring.. for one thing I would never run hv cabling where the operator(me!)
could get near it when energized and who in his right mind would handle hv
cable (or any other hv) without pulling the plug& bleeding the hv?
Really folks, it tickles me reading some of the lame subject matter on this
reflector... Now don`t take me wrong... I am no expert on building amps,but
I take pride in good craftmanship and thats paid off for me over the years!
73 all around, Jim K7RDX
