Matched Pair (2x) Genalex Gold Lion 12AX7 tube (ECC83)
Original Genalex Gold Lion ECC83/B759 tubes are considered among the best 12AX7 types ever made. They are hard to find and when they are available, they are expensive. They exhibit a large detailed soundstage that is sought after by discerning audiophiles who demand the highest quality sound. The reissue Genalex Gold Lion ECC83/B759 recreates the sound signature of the original. This tube features balanced sections and gold plated pins.

A: At first, we have to clarify that all phono preamps have a certain of background noise. It won't be loud, while a little loud is normal. Besides, there are many factors. Reason A: T11 isn't connected to ground well. While the device is playing music, picking up the GND copper part of T11 with your fingers. If the background noise is much lower, then T11 isn't connected to the ground. For this issue, we prepared a 3m wire in the package for you to solve it by yourself. Just use it to connect the GND with any large mental item in your home like windows or mental tables. Reason B: T11 doesn't match with your amplifier well. Digital amplifiers cannot be connected to the ground directly, which may cause T11 much noise. For this issue, you can just set the T11 GND switch (on the back of it) to OFF. However, this will lead to bad noise from T11 itself as it is not connected to the ground. You can only choose the bearable way. That's why we recommend using professional pure HiFi amplifiers (no Bluetooth will be better). Reason C: The RCA wire has a poor quality. A good RCA wire will be equipped with an anti-jamming magnetic ring, which can effectively reduce various interference.

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
***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 5000 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 1-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 tubes we sell are carefully packed for shipping and will have the "Riverstone Audio" name, logo and QC labels on the boxes.
