Primarily bought to replace the Fixing nut , which was originally plastic and had cracked with age.
This is the third jack socket I had bought for a similar purpose.It would have been simpler to buy just the screw nut but they do not appear to be sold separately. Possibly because it is an unusual width (maybe 3/8 '') and difficult to come by.
Yes! the nut does fit
Fitted perfectly on an old Marshall JCM 600 and also the JTM 60 amps from the early 90s.
If you need to replace those FX loops jacks, these are the ones to use.
Excellent quality Jack socket. Appears to be a good match for the 1/4” Jack input on Fostex 6301N series speakers. I bought it for the nut that was missing from my socket and it’s a perfect fit.
