Trouble is, I don't know what value to use , and it isn't marked on the schematic.
Got access to a dip meter or network analyzer? LCR meter? Pull the old cap, measure the inductance of the coil with the slugs inserted halfway...then solve for "C" at 1650KHz. Get something close, tack it in then dip the tank and check resonance.

I've had to do this many times when adding WARC bands to older Kenwood and Yaesu rigs...build your own RF and IF stage peaking coils or transformers, VCO coils and whatnot.

Let me know what you need in the way of silver mica caps if your junk box is low on them.
