Closely Matched Pair (2 tubes) of 7-Pin NIB/NOS GE JAN 5654W Vacuum Tubes. Considered one of the best of the 5654/6AK5/EF95 family of tubes for audio use. 5654W tubes are Mil. Spec. (JAN) Electron Tubes - Higher Durability and Life. Vacuum tubes were obtained from factory sealed military surplus boxes and are guaranteed to test at NOS levels.
**PLEASE NOTE** 5654W tubes can ONLY be used to replace 7-Pin 6J1, 6J1P, 6AK5, 6AK5W or EF95 tubes. Do not substitute for other 7-pin tubes or tubes with different codes. If in doubt, check with your amplifier manufacturer (or contact us) to verify that 5654W tubes can be used as a replacement in your particular audio device.
Tested and matched by Riverstone Audio utilizing the best available equipment (Amplitrex AT1000). We do not sell untested tubes - never have and never will. Our engineers match tubes for BOTH plate current and mutual conductance, with test results clearly listed on each tube box. All tubes must also pass a specialized life test and an audio sound test. The 5654W tubes selected for these matched pairs test at NOS levels at or above 5000 micro-mho and at a plate current of 7.2 mA or higher.
Only the best tubes are selected for Riverstone''s Platinum matched pairs. Fewer than 50% of the NOS tubes we test meet our standards for high fidelity audio use and are considered for use in our Platinum Matched tube sets.
Vacuum tubes sold by Riverstone Audio will have the ''Riverstone Audio'' name, logo and QC label on the boxes.
