I am rebuilding my 4.2kV PS for the 2m-8877.
That'll get you into AO-51. ;-)
I was 14 years old when working on my DX-35 with 850vdc on the 6146 plate.
I agree that many hams these days aren't not trained to handle high-voltage with all the 12vdc solid-state electronics available. But QRO sspa are running at 50vdc and higher. There are rules for safe work on HV...time to review them.
I know that's true. Even the large caps in high current 13v supplies. I thought I had things discharged and just to be sure before I started poking around with a screwdriver checking other things, I thought I would be sure the filter caps discharged, so I put the screwdriver across the terminals .....
You should have seen the spark.
