Electron Tube Testing


If you come across a term that isn't clear; for example "incremental backup" go to our FAQ Section


Tubes are tested using three separate Quality Testers:

  1. Email us first, to make sure our equipment will test your tubes.
  2. The cost depends on the tubes to be tested and quantity.
  3. Once we receive your email, we will email you back and let you know the cost for testing and shipping them back to you.
  4. We will give you payment instructions along with cost and shipping instructions.

Shipping and Handling:

  1. Pack them very well, each tube should be well rapped individually..
  2. The box should be approximately two times larger than all the tubes or larger to be safe, with plenty of packing material.
  3. Make sure the ship-to address is clear and readable.
  4. Make sure your return address is clear and readable.

The cost:

  1. Depends on tube type and quantity.
  2. Return shipping, will be by the safest methode.
