Post by dAzPost by Frank AdamI've scored a nice ATO clock recently. Freebie so it's ok. :)
It is spotless, except that someone had a go at the coil, they tried
to take the brass cover off with shearing scissors by the looks of
things. That is going to be a bitch to fix and i'll have to make a new
shell for it. Yet to take a good look at the coil, but i'm a bit
pessimistic about it's well being. :-/

nasty, I think Jaycar would have the enamelled copper wire if you need
to rewind it
Yeah, got those guys 2 minutes away. :)
Post by dAzPost by Frank AdamAnyway, what voltage were those ATO batteries ? 6 Volts ?
I'm thinking of hooking it up to a power pack instead of searching for
a battery... That is, when i get the time to actually fix it.. :)
1.5volts C cell I would think, a battery would be more stable too.
Thanks. I see that on that ATO site above.
I dont't think "C" though. perhaps a "D" or a 3-4 AAs in parallel. The
old battery was a battery pack with what seemed to be about the size
of 3-4 AAs.
I still think i'll try to go with a quality regulated power supply
though.
Post by dAzPost by Frank Adamps : If you know how many turns of wire the coils have..... it'll save
me counting it. :)
nope sorry, the kundo coil has 5000 turns on the sensing coil and 3000
turns on the power coil, of course this is for a transistor switch version.

I'm not looking forward to this. The clock is a nice piece, heavy,
about 10" square, 2" deep, skeleton in a brass framed glass case, so
it is probably worth my time to do all mechanical work, but i hate
pissfarting with electronics. :)
I'll collate the swear words and report back when i get it done. ;-)
ps: BAH! Timesavers have that battery in their catalogue for 22 bucks.
I'll probably order one now before that translates into more than 400
Aussie dollars. :)
