Fastest repair turn-around in the industry.

E-gun repair, rebuild, and magnet regaussing — every major brand.

Your gun doesn't have to be one of ours for us to fix it. We repair, rebuild, and regauss electron-beam sources from every major brand — Telemark, Temescal, CHA, and EB Sources — and we turn most of them around in one to two days. At that speed, you don't need a loaner.

What a rebuild includes

Every source that comes in gets the full treatment:

  • Stripped, cleaned, and sandblasted
  • New O-rings and screws throughout
  • Emitter rebuilt
  • Shafts, bearings, and coils checked
  • Leak checked
  • Magnet regaussed
  • Tank tested
  • Packaged and ready to run when it reaches you

Works on any major brand — our own sources, Telemark, Temescal, and CHA.

How to ship us your source

Ship to our Concord shop. Before you pack it:

  • Blow down and seal the water lines so they don't leak in transit.
  • Include the coil and the emitter.
  • Include a list of the materials evaporated in the crucible — our technicians need it to handle your source safely.
  • Pack it solid. These are heavy units and carriers are rough on them: use a sturdy box or crate with heavy foam padding that holds the source snug. No foam peanuts, no bubble wrap — light packing means shipping damage.
