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.
