Jack Input for 1980 Fender Blackface amp

[Pierrotlefol]

Hi !

I am new to this forum. I came here to find help for my first amp repair project. I got a 1980 Fender Blackface Montreux from a friend and it has a broken input jack. I want to replace but I cannot find similar jacks on the internet. I am wondering if I could use one that is not exactly the same? It seems like it only has 3 pins. Here what it looks like :

There are many suppliers of these type of sockets.
Mainly 5 pin (cut off the unwanted patterns). Personally, for reliability, I fit Switchcraft L12A sockets instead of those junky cheap plastic Fender ones.
A version of the original is to be found here; https://www.allparts.uk.com/products...ive-to-9029001
Don't know where you are so cannot be more specific.

That allparts jack is from a different era of Fender amps. I'm not sure if the footprint or height off board will line up.

The original part is Switchcraft RN112APC. You can get it from most larger electronic suppliers like mouser, newark, digike, etc..
