[Amps] 4CX1000A project

[Al Kozakiewicz]

Just FYI, from Wikipedia: 

MHV connectors are presently considered by some as a safety hazard because of the possibility of high voltage on the exposed central pin when not plugged in,[1] and because the ground connection is broken before the power connection when demating. SHV connectors are designed to prevent these hazards, and cannot be mated to BNC connectors.

Always have liked the idea of separate power supplies but have always worried about the safety of interconnects.  The one other person I know who did this did not use any connectors for the HV.  Accomplished the goal decoupling the supply from the amp, but requires tools and time to move either chassis more than the length of the umbilical away from each other.

I've added a few more photos to my 4CX1000A amplifier page at <http://www.qsl.net/k2vco/4CX1000A/K2VCO%204CX1000A%20Amplifier.html>

I finished the wiring as well as testing and adjusting the Tetrode Boards, which include the screen and bias regulators and trip circuits, the warmup timer, etc. I have not yet applied HV, which I intend to do when I'm fresh, and after I've cooked the tube with heater voltage only for a while.

I'm working on adding fans to a '1000 watt' Drake dummy load to use for testing.
