You are purchasing a "Platinum Plus Grade" matched pair of tubes. This means that the plate matching is virtually perfect on a calibrated Hickok TV-7 or 799 within 1%.

These tubes were carefully screened by the manufacturers (Baldwin,Conn,Wurlitzer, Lowery etc.) and specially selected for their low noise and microphonic characteristics. This makes them ideal for your preamplifier and phono stage applications.

Please see our other listings for "Silver, Gold and Platinum" tubes. 

Silver Grade tubes are matched within 15%, Gold Grade within 10% and Platinum 5%.

The Gold and Platinum Grade pairs are recommended for more critical applications such as your preamp and phono stage.

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.
