***IMPORTANT: 5654W tubes can ONLY be used to replace 7-pin 6J1, 6J1P / 6J1P-EB / 6Zh1P-EV, 6AK5, 6AK5W or EF95 tubes. 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. AMPLIFIER DAMAGE CAN OCCUR IF YOU USE THE WRONG TYPE OF TUBE AS A REPLACEMENT*** Package contains a closely matched pair (2 tubes) of vintage US-manufactured GE JAN 5654W vacuum tubes. The tubes are Amplitrex TESTED and MATCHED, and subjected to multiple test cycles to determine stability. Plate current and Gm are both matched to within 3%. Matched tubes undergo a final audio sound check to make certain they are indeed audio quality. With our high standards, FEWER THAN 40% of the NOS 5654W tubes we test are considered for use in these special matched pairs. 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 4800 micro-mho or higher and a plate current (ip) of 7.2 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). As a US seller we stand behind our products and back our Platinum Grade tubes with a no-nonsense 2-YEAR WARRANTY - THE BEST WARRANTY IN THE AUDIO TUBE BUSINESS! 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.

Riverstone Audio - Tested/Matched Pair (2 Tubes) 7-Pin GE JAN 5654W Fully-Tested Vacuum Tubes - Upgrade for 6AK5 / 6J1 / 6J1P / EF95 - GE 5654W Platinum Grade Pair

Product review & video

hi I'd like to to discuss how we match tubes using the hiccup 539 be the particular lot that I want to let that now is the general electric JN 5654 tubes we receive these in sealed boxes beautiful condition for the boxes and the tubes inside this particular lock they come in boxes of 200 came out of Utah and we bar these for a monster plus dealers an important thing is they're in sealed boxes and particularly they come out of Utah they'll be beautiful just from the climate control and let me show you what we see inside pop this one up so again these have been sealed since 1988 it's getting harder and harder to come by now and the sealed boxes so we've got in this particular box 200 of the 56 54 W which is the ruggedized military version of a 56 54 it's a great substitute for a 6j one tube in a headphone amp or a preamp or an audio amplifier and also a very good substitute tone there upg
