Thinking about this some more, I think there are just two main parts to this piece.
The wire, and the ferrite core. If the wire is burnt out, you can rewind the coil
without too much trouble. You would use similar gauge enable covered wire
and the number of turns should be the same as the original. If the ferrite core
is broken, then simply find someone with some tunable inductors, or IF transformers,
and steal a slug from another one. Either of these things should be easier than
finding a replacement, unless you can get one off of a M6 or M6R scrap pc board.

That is a variable inductor, listed on the
schematic as variable

between 3 uH and 7 uH. It is not a transformer, even
though it

may look like an IF transformer.



Are you sure the old one is bad



A quick search on the web makes me think you will have
trouble

finding an exact replacement. Inductors add in series, so
if you can find

a slightly smaller one, then you could add a fixed inductor
to it to

get the value that you need. You need to be able to hit a
specific oscillator

frequency by adjusting the tuning slug, as described in the
service

manual.



Probably the easiest would be to get one off of a junk M6 or
M6R board.

hi!

my

component L3 is dead (an IF coil transformer)if you got

infos that can help me to find another one, it would be

dope!!!



mny thanks!
