WTB: HV coil for Emerson 610 or 600 electrostatic CRT TV (Alive or DEAD)

I am in need of the HV coil for the Emerson 600 or 610 7 inch electrostatic
CRT TV. Mine is open.

Experts out there: maybe one from a similar set using the same 6kV CRT
will do??

Edit: I realized that a dead one, so long as it looks OK,
will probably be useful, as mine likely has only one dead pie.
A dead one would supply a good pie that could be hacked in.

You only have a short time (30 mins?) to edit the subject before it gets locked in.

I see.

In any case, there is now hope the coil is OK. I removed it from the mount
and resoldered the wire on the bottom, its now 650 ohms which
seems similar to other 7" electrostatic deflection TV coils. I can
now get an arc from the (unconnected) coil HV lead and
my 2 Gohm HV probe, and with +4kV DC from my lab
power supply applied to the cap
of the 1B3 I get a raster ... but I think the 1B3 is gassy
as it glows purple. Getting a new one is the next
agenda item. The vertical deflection is all
wrong, but there is plenty of it. The horizontal is OK.

Edit: I'll close this topic and use the one is electrical repair.
