Note:

  1. A few tubes are new or that were used briefly for substitution while servicing equipment, but most are used that were removed from obsolete equipment, however every tube is tested and I only sell those that still show lots of life and do my best to accurately describe each tubes condition when replying to enquiries along with tube & shipment costs.

  2. Determining what one should list tubes for is time consuming and listing items takes enough time as it is, so listed costs are simply 75-80% of the average price found on several favorite web sites with the lowest pricing I've found and
    (a) what I have listed is charged for new tubes and those that test as good as new,
    (b) less is charged for tubes testing less then 100% depending on their condition,
    (c) and, as always, a further discount is given for larger orders.

  3. Nostalgia Air and Radio Museum are my favorite tube substitution web sites for when one has trouble finding the exact tube required.
  4. Check the Tube Sockets, Shields & Other Tube Related Items page for additional items.
  5. Unless noted otherwise, test results are from a B&K 707 DynaJet Dynamic Mutual Conductance Tube Tester.
