Each tube is precision tested and matched within 3% for plate current and mutual conductance, guaranteeing NOS-level sound quality and reliability. Ideal as a direct replacement for 6J1, 6AK5, and EF95 tubes, these tubes come with a 2-year warranty and are trusted by professionals seeking authentic vintage audio upgrades. ## Description 5654W tubes are a direct substitute for 7-pin 6J1, 6J1P / 6J1P-EB / 6Zh1P-EV, 6AK5, 6AK5W, EF95 and 403B tubes. For other substitutions, check with your amplifier manufacturer - amplifer damage can occur if the wrong type of tubes are used. Plate current and Gm for the tubes are matched to within 3%. We guarantee that these tested/matched 5654W tubes will test at NOS levels, with Gm above 4500 micro-mho and a plate current (ip) of 6.5 mA or higher (Amplitrex tested in fixed-bias mode at plate and screen voltages of 120 V and grid voltage of -2.0 V). The vacuum tubes are carefully packed for shipping and will have Riverstone Audio name, logo and QC labels on the boxes. The 5654W vacuum tubes are backed by Riverstone Audios 2-year warranty. 5654W tubes were originally designed as a low-noise upgrade for 6AK5 and EF95 vacuum tubes. The "W" designation refers to ruggedized military-grade tubes with better quality control and enhanced reliability. These vintage tubes have found new life as a replacement for 6J1, 6J1P (6ZH1P-EV), 6AK5 and EF95 tubes and are used by audiophiles for improved sound quality. ## Features - Tested and matched pair (2 tubes) of low-noise 7-Pin NIB/NOS JAN 5654W Vacuum Tubes. Considered one of the best of the 5654 / 6AK5 / EF95 family of tubes for audio use. - Our platinum Grade 5654W vacuum tubes are matched within 3% for both plate current (ip) and mutual conductance (Gm) and are backed by a no-nonsense 2-year warranty. - We guarantee that the 5654W tubes selected for our Platinum Grade matched pairs test at NOS levels at or above 4500 micro-mho with a plate current of 6.6 mA or higher. All tubes must also pass a specialized life test and an audio sound test. - Riverstone Audio Platinum Grade tubes are provided with data labels showing measured ip and Gm. - Amplifier damage can occur if you substitute the wrong type of tube. 5654W tubes should only be used to directly replace 7-Pin 6J1, 6J1P / 6J1P-EB / 6Zh1P-EV, 6AK5, 6AK5W and EF95 tubes. DO NOT substiture for other types of 7-pin vacuum tube unless approved as a substitute by the manufacturer of your audio device. - AN 5654W tubes, and many other vintage US-manufactured vacuum tubes, used water-based silk-screen printing for final tube-markings. As the print is water-based, the original green-color print may be faded or partially missing due to the age of the tubes (the manufacture of 5654W tubes ended approx. 35 years ago). However, determining the authenticity of a 5654W tube is straightforward, as both "5654" and "USA" were etched into the glass during the original manufacturing process (this white-gray lettering can be seen in one of the listing images). The green print was used by the orignal factory to denote details such as "JAN 5654W", "Made in USA", factory logo and date and factory codes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01BFJDTW0 | | Best Sellers Rank | #8,448 in Musical Instruments ( See Top 100 in Musical Instruments ) #24 in Amplifier Accessories | | Brand Name | Riverstone Audio | | Colour | multicolour | | Country of Publication | USA | | Customer Reviews | 4.8 4.8 out of 5 stars (1,875) | | Item Type Name | vacuum tube | | Manufacturer | Riverstone_Audio | | Manufacturer Warranty Description | no warranty available | | Material Type | Glass | | Maximum Pressure | 7 Bars | | Nominal Wall Thickness | 1.3 mm | | UPC | 763769918220 | | Unit Count | 2.0 Count | ## Product Details - **Brand:** Riverstone Audio - **Colour:** multicolour - **Manufacturer:** Riverstone_Audio - **Material:** Glass - **Maximum Pressure:** 7 Bars - **Net Quantity:** 2.0 Count - **Nominal Wall Thickness:** 1.3 mm - **Number of Packs:** 1 - **Set Name:** JAN 5654W Matched Pair (2 Tubes) - **UPC:** 763769918220 ## Images ![Matched Pair (2 Tubes) JAN 5654W Fully-Tested Vacuum Tubes 6J1 / 5654 /6AK5/ EF95 / 6AK5 Tube Replacement - Image 1](https://m.media-amazon.com/images/I/51rFMXgNTRL.jpg) ![Matched Pair (2 Tubes) JAN 5654W Fully-Tested Vacuum Tubes 6J1 / 5654 /6AK5/ EF95 / 6AK5 Tube Replacement - Image 2](https://m.media-amazon.com/images/I/51GoXUg-nXL.jpg) ![Matched Pair (2 Tubes) JAN 5654W Fully-Tested Vacuum Tubes 6J1 / 5654 /6AK5/ EF95 / 6AK5 Tube Replacement - Image 3](https://m.media-amazon.com/images/I/51TOpuU6TEL.jpg) ![Matched Pair (2 Tubes) JAN 5654W Fully-Tested Vacuum Tubes 6J1 / 5654 /6AK5/ EF95 / 6AK5 Tube Replacement - Image 4](https://m.media-amazon.com/images/I/51ueO8RRQHL.jpg) ![Matched Pair (2 Tubes) JAN 5654W Fully-Tested Vacuum Tubes 6J1 / 5654 /6AK5/ EF95 / 6AK5 Tube Replacement - Image 5](https://m.media-amazon.com/images/I/51-UUY5asVL.jpg) ## Questions & Answers **Q: Is it works with nfj & fx audio tube 03 preamplifier** A: It's a great direct replacement for the 6J1 tube.
