I acquired this integrated amplifier. The shielding on the single-ended input jacks has been pulled off. I've already removed these from the board and am looking for parts that will fit. I've already contacted Krell. They were very nice but not able to help. I've searched Digikey, Mouser, AliExpress, etc. and haven't found anything that would fit perfectly without modification.
As far as modifying parts that I have found goes, that would involve trimming off the screw hole on one side of a connector that has screw holes on both sides or it would mean buying a 2x2 and 2x3 and not using all of the available screw holes in the chassis. Maybe there are other suggestions?
I'm wondering if anybody out there knows of where I might find the right part OR has any ideas about how to otherwise make this work? TIA, mfaughn.

Good evening, vintage parts are often not easily available unless you have an identical device with the connectors in good condition.
An alternative, in my opinion, could be to use a base like the one below and subject it to a small modification to adapt it to the back panel.
In this case, you can cut it in 2/3 in order to have the two separate parts you need and drill the holes on the side in correspondence with the panel. Probably the old screws are no longer adaptable and bolts with nuts are needed, in any case the final aesthetic result could be acceptable (functional)

The board goes in above the jack, which would hide the solder terminals on the jacks shown above. That would make it onerous to solder leads between the board and jacks. I guess I could make the leads quite long but that doesn't sound nice. Finding something that PCB mounts that I can work with will probably be much easier.
Doing a google search for "dual pcb mount rca jack" came up with a bunch of pcb mount jacks that look like they could work. CUI, Kycon, uxCell, etc.
These should fit, it's a standard footprint.

Nope. Different footprint. See how the ground pin on mine is oriented towards the other side and not under the connector as it sits on the PCB.
Strange re: contacting Krell, as the current 300i looks like it uses very similar connectors, at least from an exterior view.
Barring finding anything that you could modify, you could buy individual RCA connectors and wire them in. PITA, but should work.

Instead, how about replacing the missing gold-plated casings after removing them from similar connectors?
It's a bit laborious but perhaps doable, anyway the last connector at the bottom which is broken would have to be repaired prior with epoxy...

I ordered some connectors from China this morning (AliExpress). They aren't perfect fits but I'm hoping I can make them work. If not, I'll probably just go with individual panel mounts and figure out how to best route leads to the board. Thanks all!
It looks like cliff part middle pin is gnd and up/down RCA pin direction looks like same with your board.Maybe it helps.
