I have a Hafler Pro2400 power amp that has the separate XLR / TRS input jacks. Turns out that the circuit board that has the mounted TRS jacks/XLR ins is pretty-much held in place by the hex nut rings that snug the TRS input jacks to the chassis. And these TRS inputs had plastic threaded shafts. So, I noticed a lot of play in the jack (and I'd been having some signal drops on this amp) so I tightened the nut on the TRS thread... low & behold, I overtightened it, and sheered the outer-most threads of the TRS input jack. Now I can't secure the nut (shut up, VVV!) / which leaves the circuit board kinda floppy.
I have the manual, and the manual has a parts list / schematic... but I really just need to know what modern equivalent part is gonna surface mount exactly in place where this older TRS jack is. The parts list calls it: "PC Mount Phone Jack, CCH-208" (as shown below)

Here's a photo of the part — it's the black & silver "box" right above the DH1 designation on the PCB.

I'm handy with a soldering iron, and I'm confident I can cleanly desolder / re-solder... but I definitely don't want to buy the wrong part. It doesn't seem like CCH-208 means anything to Mouser / McMaster Carr / Digikey... so I suppose this is the "Hafler part #", and since these are legacy, I don't imagine I'm gonna get much love calling them up to ask (especially because their website says clearly: "we cannot offer support on legacy units...")
So if anyone can help me figure out how to locate the best search terms to use, so that I can find the most appropriate current part, I'd really appreciate it.
