May I suggest using a 120 to 240 volt transformer. These are avail at local
electrical suppliers at current ratings up to several amps if you have he
money. Then modify the rectifiers to a voltage doubler. This should get you
very close to your 560 volts with a cap input filter.Get a xformer with taps
and you can tweak the voltage a bit. I have a couple of 120 to 480 xformers
with taps. Unfortunately they are rated at 2KVA. may be a little over kill.

No funds to buy new PCB. Not up to making a PCB now, later sure.
Stripping with the iron is right here, easy and a small time expenditure.

Ah, it's just an exploratory one-off, so far, naive as that may seem -

a cheap kick-in to actually beginning prototyping, don't worry about it:-)

I have some - and I have a guillotine that I may be able to chop this
with.
The tags I have are better than the tag-strips. Extra holes are no
problem.
Most of the traces are wide and easy. Still, I understand your reaction:=)
It's just a no/low-cost trial, utilising the available resources:=})
