I’m helping in a Repair Café and yesterday someone came in with a Boss BX-80 Mixer that has a broken jack socket.  
I found the service manual for the Boxx BX-8/16, in that it’s said that the jack sockets are hlj0521-01-110  
Assuming the BX-80 uses the same parts, could someone recommend jack sockets that would fit?

It’s the second channel input, so pretty sure it’s mono.  
I thought of taking a picture of the Mixer model, but not the jack sockets themselves.

The ones from retroamplis look very much like what I remember: relatively long but narrow and very close to the PCB.  
I guess I’ll make the person measure them exactly
