6 Pin XLR replacement on Marshall TSL 100 (JCM 2000)

[Markusv]

Folks

I am doing some repair work for a backline audio rental firm
They have a few TSL100's with 1 common problem:

The amps come back from rental and the footswitch malfunctions.
It seems people yank the XLR cable where it plugs into the back of the amp and for instance the reverb switch stops working because the pins bend

We want to install more robust, non- PCB mounted XLR sockets into the amps to avoid this from happening in future

With this I also want to change the jacks that attach to the cable coming from the footswitch

What is a good source?
Good brand?
Any suggestions please and if you have a link I would appreciate it very much!
