## Questions & Answers

**Q: Do I just plug them in and start playing music or let them burn in for 10 hours first?**
A: Thank you for your question. First the quick answer...5654W tubes used in Riverstone Audio's matched tube pairs and quads have undergone extensive testing and are ready to use...so plug, play and enjoy. And now the longer answer...There are varied views on the effect of tube “burn in” on sound quality and if it is necessary. From a technical viewpoint, during initial use, there may be small changes in the electrical characteristics of a vacuum tube, including changes in cathode emission.  For a given circuit, these initial changes may influence how a tube “sounds” in a particular audio device.  For a headphone amplifier or other audio device, and depending on how a tube is used in a circuit (e.g., tube-based or hybrid circuits), detectable changes in sound quality, if any, will usually occur very early in the use cycle of a tube.  However, for some tubes, you may continue to hear subtle changes even after 10 to 20 hours of use.   Changes in electrical characteristics, which depend on the chosen operating point of a tube (e.g., plate voltage) are measureable and can be documented by monitoring a tube’s electrical parameters as a function of time.  For the 6AK5/5654 family of tubes, we find that measurable electrical properties stabilize within the first several hours of use and, in fact, for many of the 5654/6AK5/EF95 tubes we have examined, stability in measured parameters is often achieved after less than an hour of use (the rate at which the parameters stabilize during initial use depends on the chosen operating point of a tube, such as plate voltage and grid bias).At Riverstone Audio we utilize detailed screening and test procedures for our matched tube sets.  To screen out low quality tubes, and to help stabilize the electrical characteristics of the tubes used in our matched tube sets, we subject the tubes to several test cycles that incorporate an extended hold period during which key electrical parameters, such as plate and grid current are monitored for stability (drift).   As part of our QC procedure, all tested/matched tubes sets are checked for noise AND sound quality.  The sound quality test is performed using a headphone amplifier by technical staff well trained in the nuances in sound quality for various types of tubes – tubes that do not pass the electrical parameter tests, noise, or final sound quality checks are discarded.Our matched 5654W and 5670W tube sets are the most extensively screened and tested vacuum tubes available anywhere.   So..plug, play and enjoy and rest assured that the tubes are ready to use.  James at Riverstone Audio

**Q: will this replace 6K4 i bought a headphone amp on here and it list this tube as a replacement for 6K4 so will this work**
A: 5654W tubes are not a direct substitute - however, certain hybrid circuits using the Chinese 6K4 tube are designed such that several other 7-pin pentodes can be used as replacements Note that there is also a vintage Western tube that is also refered to as a "6K4 tube:; this tube is a sub-miniature TRIODE and IS NOT a substitute for the Chinese 6K4 tube as they have much different electrical characteristics and physical connections (the vintage US-manufactured 6K4 triode has electrical leads that are soldered to a circuit).  The closest Western equivalent to a Chinese-manufactured 6K4 tube is the vintage 6BA6/EF93 pentode.  Again, as mentioned earlier, some headphone amps and tube buffers that are available on Amazon have hybrid circuits that allow using several different 7-pin pentode tubes in place of the Chinese 6K4; including 5654/6AK5/6J1 tubes. Before ordering any tube, please check directly with the amp or buffer seller to verify that your particular amp or buffer model can utilize other 7-pin pentode tubes.  Best regards, James at RIverstone Audio

**Q: Do these riverstone audio - tested/matched pair (2 tubes) 7-pin ge jan 5654w work for my little dot mk1 + and my little dot mk ii as driver tubes ?**
A: Yes, GE JAN 5654W tubes are excellent driver tubes for both the Little Dot mk1+ and Little Dot mk ii headphone amps.  We have several of the Little Dot amps in our workshop and have tested these tubes, and many other US as well as Russian tube brands, extensively in both the mk 1+ and mk II; when properly chosen the JAN 5654W consistently rank the highest in terms of sound quality and low noise level.   The test parameters we use during a portion of the electrical parameter testing were chosen based on the circuit requirements of the mk 1+ and mk II headphone amps. 
James at Riverstone Audio

**Q: Do these tubes come with all the lettering intact or is the lettering worn off**
A: We only sell vintage tubes that have good quality lettering. We inspect each tube to make certain that the lettering (tube type, manufacturer and date code) is readable on a tube - if it does not meet our requirements we simply do not sell the tube. The lettering will not always be "perfect", but it will generally be in very good condition. As background, the lettering that was used on many vintage US-manufactured tubes was often applied by silk-screen printing, which is less than ideal in regards to abrasion resistance of the lettering during shipping and routine handling. During shipping, surface abrasion, caused by movement of tubes within their boxes can damage to the print. In addition to abrasion during shipping, improper handling and cleaning of tubes can significantly degrade the quality of the 30+ year old lettering on 5654W tubes. To help preserve the lettering on the 5654W tubes we sell, we utilize thick EVA pads to prevent tubes from moving in their boxes. The EVA also helps absorb vibrations and impacts during shipping. We have gone the extra mile to provide good quality tubes, and want to make certain that the tubes you receive are protected from damage during shipment. If you ever receive tubes from Riverstone Audio that you are not completely satisfied with simply contact us for a refund or replacement.
James, RIverstone Audio

### ⭐⭐⭐⭐⭐ Review
*by M***E on 14 September 2025*

This alleged matched pair of 5654W vacuum tubes were my first tube purchase from Riverstone Audio. Very impressive packaging – safe, secure, and it looks like they take pride in their work. As I do not have access to a tube tester, I have to take Riverstone’s word on them being matched and on their measured performance specs. These tubes replaced the cheap Chinese crap tubes that came with my equally cheap Douk Audio T3 Plus phono/headphone preamp. The T3 Plus itself is underwhelming, but for the price that’s what I expected. However, for relatively little money, these 5654W tubes made a subtle but very noticeable improvement in sound quality in my T3 Plus. And that improvement was well worth the cost of these tubes, regardless of the following concern: HOWEVER – and I’m hoping Riverstone reads and responds to the following comment – I am a little concerned that these 5654W tubes may (or may not) have been counterfeit, or not completely advertised honestly as real GE NOS / New Old Stock tubes (actual NOS means they were manufactured many decades ago in tube’s “muscle car era” and have never been used since. Such NOS tubes command very high prices now, due to their reputation and scarcity). Here’s my concern: The green ink printed labels on the outside of each tube appear to be printed over, and on top of, other labels in light gray ink that appear to be on the inside of the tube - question mark ( ? ). Hmm. While this is unlikely to be an actual problem, our friend The Internet is full of counterfeit knock-off tubes that are “advertised” as NOS / New Old Stock but are actually modern tubes that are not manufactured to the same old-school tolerances and specifications. Similar to cheap Gucci and Louis Vitton handbags, etc. As these Riverstone 5654W’s have both green and gray printed labels, one on top of the other, it makes me doubt their true manufacturing / vintage. That said, they sound better than the tubes I replaced them with, and that’s all that really matters. In addition, a deep dive into research on GE 5654W tubes from other vendors also shows them as having the double green/gray printed labels, so at least these Riverstone’s are no worse than that competition. All that being said, for the asking price, these Riverstone 5654W’s are well worth the asking price – they simply sound better than the cheap factory installed tubes I replaced them with, and for less than the price of dinner out this evening. As this 5654W tube and its numerous compatible variants are not commonly used by tube amp/preamp manufacturers, it’s difficult to get trustworthy research on them no matter which vendor you consider. Even tube “Godfather” Brent Jessie’s website has scant info about this tube family, and Brent Jessie’s website is the most trustworthy for vacuum tube research.
