You are purchasing a Platinum Grade matched pair of tubes. This means that the plates are very tightly matched on a calibrated Hickok TV-7 within 5%.
These tubes were carefully screened by the manufacturers (Baldwin, Conn, Hammond, Lowery, Wurlitzer etc.) and specially selected for their low noise and microphonic characteristics.
Please see our other listings for "Silver, Gold and Platinum Plus" tubes. Silver Grade tubes are matched within 15%, Gold Grade tubes within 10% and Platinum Plus 1%.
The Gold and Platinum tubes are recommended for more critical applications such as your preamp and phono stage.
The price listed is for one pair of tubes. To purchase more than one pair, 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.
