Default Re: IF fault on Eddystone 770R

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.
