Need part for Altec P-518-A Mic power supply

[Richard Links]

Hello:

I have a 1950's Altec P-518-A power supply, which goes with one of their old
tube "coke bottle" microphones, in this case, one with a 21-B omni capsule.

I accidentally damaged the panel-mount Canon type P-8-13 on the power supply
itself while removing a mic line. This is a provision for an 8-pin mic
connector (plug).

Does anyone know of a good source for a replacement of this sort? Again,
this would be a request for a replacement of the panel-mounted socket, not
the plug, which is fine.

Thanks in advance!
