Matched tubes undergo a final audio sound check to make certain they are indeed audio quality. With our high standards, 5654W tubes were originally designed as a low-noise premium-grade substitute for 6AK5 and EF95 vacuum tubes. The "W" designation refers to ruggedized military-grade tubes with better quality control and internal design changes to enhance reliability. These vintage tubes have found new life as replacements for 7-pin 6J1, 6J1P (6ZH1P-EV), 6AK5 and EF95 tubes and are commonly used by audiophiles for improved sound quality. When received, we guarantee the tubes will test at NOS levels of 4400 micro-mho or higher and a plate current (ip) of 6.4 mA or higher (tested in fixed-bias mode at a plate and screen voltage of 120 V and a grid voltage of -2.0 V). NOTE: Some amplifiers, such as the Little Dot 1+, MK II and MK III, may require circuit board jumpers to be changed when swapping tubes (procedure is outlined in the Little Dot manual). All vacuum tubes we sell are carefully packed for shipping and will have the "Riverstone Audio" name, logo and QC labels on the boxes. * Order Cancellation Policy ** You can return a product for up to 30 days from the date you purchased it. 1.
