NEC KM-511SM monitor coil L701 part No. RCHO-2688d8 SYE-9750

i need to rewire a coil that's part of the B+ circuit in a monitor.
the problem is the original wire is stranded(18 strands) 0.8mm thick and
i can only get the solid core stuff.
if i replace it with a similar thickness wire, will it do the job?
i don't have an inductance meter so im limited to multimeter and a
flyback ring tester.
a good coil(from another monitor) measures 1.3ohm and lights 7 led's
on the ring tester.
my plan is to wind it with the same length/turns as the original wire
then measure the resistance and ring it to see how many led's light up.

If you can't get the right wire, can you get insulated winding wire which is
the same diameter as the individual strands? You might be able to make
your own Litz wire, but be careful because the way the strands are twisted
might be important so try to copy the original. If the monitor is for your
own use, you'll probably be ok, but I would hesitate to perform this kind
of repair for a member of the public.
