I would remove the coil. Just make a diagram of the color codes etc.

Once you remove the can from the chassis it will be obvious how to
disassemble it.

The reality is that the cap is probably OK but that the coil is open. You
may find that a connection to the coil on the form may have corroded. I have
in the past been able to repair an open IF can by finding this open
connection and then unwinding one turn and reconnecting to the terminal

Good Luck

Hi.

I suspect that the capacitor for the 10.7 MHz filter on one of IF can
of my SX-42 is shot. I've been reading about the problem with the
silver mica caps on IF cans here but I don't know whether the SX-42
has these caps in the IF cans.

This is my first major boatanchor restoration and I already replaced
all paper wax caps and electrolytics and checked all tubes. LO works
fine on both frequencies. AM works great but the FM is dead (or
anything on the 2 upper bands that use the 10.7MHz IF filters. I can't
pass a 10.7MHz modulated signal through the 2nd IF stage. An
interesting thing I noticed is that when I inject a 455KHz through the
2nd IF stage and switch the band to the upper 2 (FM bands) the signal
gets stronger.

Question: is there a way to disassemble the IF can in the chassis or I
have to remove it? How do I disassemble it?

Also, what is the value for the capacitor on the 10.7MHz part of the
IF can?

Thanks for the help.
