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.

Bob
