Have thrown together some parts on a plank here. The idea is to make a “lean” power supply to test my crowbar circuit.
Output is 630v with the current limiter (spot light bulb @ 120watt). And the capacity of the filter capacitors is about 1100uF.
This should be enough energy for the preliminary circuit tests.

Here is a line of homebrew circuit board that I have made for a amplifier project I am working on. (Which by the way takes forever to comlete )
These boards are designed by Dominique F1FRV which have laid down a tremendous effort in designing these boards.
Dominique has done some minor changes to the design since these boards were made, so cards made by his latest instructions will look a bit different from these.
