Hello, I'm glad to find this group as I've been reading the ezboard
web forum but it appears to be more or less deceased. I'm in the
process of building the basic, simple, original Alastair Couper
desulphator comprising 13 components.

I either already have, or can order all of the components but the
chokes are throwing me for a bit of a loop. I've consulted with
someone much cleverer than I (I'm an electronics ignoramus) who
advised that two chokes I'd selected as potential candidates would be
unsuitable as they're only rated for 155mA.

I can get the 220uH choke rated for 5A, and a 1mH (which I presume to
be the same as 1000uH) rated at 1.6A. Would this be sufficient? If
the lower current ratings will do that would be great because they're
significantly cheaper, but since I'm only making 4 it probably won't
matter that much.

Also, will it be ok to substitute a 33uF 25V for C1 (should be 30uF
16V) and 100uF 25V for C4 (should be 100uF 16V)?

Any advice gratefully received.

Cheers,
Ash
