The capacitors are indeed mounted inside the IF can as can be seen from the attached. Capacitors are polystyrene 100pf 125v, and are mounted across IF can pins 4 & 6, and 1 & 3.

I completely rebuilt my 770R Mk1 some years ago and took many digital photo's together with drawings to ensure it all went back together correctly. To rebuild the audio unit I removed it from the main chassis. It means cutting into the wiring form and removing a few bolts, but so much easier to get at all the components. I am still using the receiver together with a rebuilt 770U Mk1 and EP14 Panadapter.
