Description

All tubes come with a full 30 day, unconditional, no questions asked, money back satisfaction guarantee! Test scores will average between 80% and 90% of NOS values. Individual test scores will be written on the boxes that you receive with your tubes. These tubes were carefully screened by the manufacturers (Baldwin, Conn, Hammond, Wurlitzer etc.) and specially selected for their low noise and microphonic characteristics. You are purchasing a "Gold Grade" tube. This means that the plates are very tightly matched on a calibrated Hickok TV-7 or Hickok 799 within 10% . Please see our other listings for "Silver, Platinum and Platinum Plus" tubes. Silver Grade tubes are matched within 15%, Platinum Grade tubes within 5% and Platinum Plus Grade 1% . The Gold and Platinum Grade tubes are recommended for more critical applications such as your preamp and phono stage. The price listed is for one tube . To purchase more than one, when available, simply change the number in the quantity box which is located just above the advertised price. Please email with any questions and/or concerns.
