OT mk1 Headphones out ”thing”


I found this plastic ”thing” on my 1970 VOX cab and it fits, but what is it called and where to shop the spare part?

I think they’re called “dress nuts.” Not sure where you’d find them in your area, but here’s a lead…

Thanks, googled plastic dressnuts Marshall and Vox Plastic Nut for Jack | Parts Is Parts - Guitar Parts, Amplifier Parts, Korg Keyboard Parts
But wonder which thread there is on Octatrack mk1? ”Fits most Marshall and Vox jacks, there are some Vox jacks this nut will not fit on.” My VOX dressnut fits but I need it on the VoX.
” Electronic components for 1/4" (6.35mm) jacks do not use generic hardware-store threads. The specific standard thread size you need to look for is:

  • Thread Type: 7/16" - 20 UNF (Imperial thread standard).
  • Material: Black Nylon / Polymer plastic.
  • This size is used almost universally across standard PCB-mounted plastic-nose synth jacks, notably on Cliff S2/S4 series sockets and Jalco variants
