John,
The board you have is the very first SC100 rev A, which had slightly
different component values.
If the only thing broken on the inductor is the top ferrite screw cap,
then you should be able to swap it form the coils I have. If not, you'll
have to change it out. I can supply matching 50 Hz capacitors. They are
.018 uF, as I recall. They are a special PPS formulation for temperature
stability. They are also no longer sold.

that's good news. The ones from the kit are numbered 9478 T1104.
The T1105Z are I believe 8.2 mH. So now I show my ignorance : ) what
difference does a few mHs make?
For info I found a .pdf from digikey
http://media.digikey.com/pdf/Data%20Sheets/Toko%20PDFs/7PA,%207PLA%20%28Variable%20Coils%29.pdf
Are the ones you have 1104? If so if you would like to PM me we can sort
out price and payment etc.
Very much appreciated
Regards
John

Yes, I have a little box full of those exact coils. Yay!

I know this is an old clock kit but I have one and I would like to finish
it.
I know there are others around but I like the older stuff.
I have managed to break one of the variable inductors L1.
Does anybody out there have a an unmade kit/knackered kit which is good
and would like to part with it?
Hopefully that won't be necessary. That's David Forbes' design, so
hopefully he'll tell you where he got the part
originally, or the part number so you can source it yourself from a UK
vendor.
It's an 8.2mH adjustable inductor, according to the parts list.
My best guess is that's a Toko 126ANS-T1105Z.
