Mayware / JH Labs Formula 4 arm mods.

History: transcribed from hand written notes – author unknown. From a good few years ago by all accounts.

Not known if these notes refer to JH labs version or Mayware version. There is a reference to a sliding cursor – does this help anyone? I’ll update these notes if this can be determined for sure.

The author was plainly very happy with this arm after these mods J

My own notes are in italic.

Modifications:

  1. All mechanical connections (except arm tube to centre hub) glued with epoxy. This made the sound smoother and less harsh.
  2. Headshell heavily damped with ‘Movtite’ (spelling? – what is this stuff. Anyone know?). Made a large improvement in smoothness and solidity and transparency of sound.
  3. A band of Movtite added around middle of the arm tube. Results same as 1+2.
  4. Sliding cursor removed – it resonated- also smoothes out the sound and stabilises the image.
  5. Arm completely rewired with Teflon coated silver wire (single Vs stranded – doesn’t say). Made a huge improvement in airiness, cleanliness, imaging depth etc. Silver wire is amazing in its ability to ‘open up’ and add life to the sound.
  6. Phono leads replaced with custom pure silver (signal wire and ground jacket) leads. Wire costs $33. This is soldered to the terminal strip and hardwired into my preamp. This is fantastic. I replaced Fulton leads throughout my system with this cable. It’s by far the best sounding cable I’ve ever heard. The sound is open, alive, immediate, airy etc. etc. I just can’t say enough about it.

The arm is now tremendous. Smooth but alive and with tremendous depth imaging and airiness.
