Achieving the right Cap Size

[Active8]

I agree with you, this is not a circuit to play with unless you really
know what you are doing. Two other things it should have (if one still wants
to use this circuit), is a fuse (in case C1 should short out) and a
polarized plug (so that the "-" side is always near earth ground).

Ahh but I've seen so many places with reverse polarity.

Looking at the OP's circuit again, I find that it uses a bridge
rectifier - so there will be NO "right" way to plug it in. The
output will always be hot.

Oh. I wasn't able to get any web pages - had to reboot after maybe a
month.

You are right.
