Shuguang EL34-B Power Vacuum Tube (Matched)
Need matched power tubes? Don't worry! Price includes matching in any quantity you need for no extra charge. Need a matched pair? Just order "2" tubes. For a matched quad order "4" tubes. Matched sextets and octets are available as well.The Chinese (Sino) made Shuguang EL34-B vacuum tube is sold by Ruby Tubes as their EL34B-STR and was much loved by our reviewer. From our review of this EL34 tube: "The sound is loud and clear with a very nice sonic range. Not excessive in tops, mids, or bass, they are accurately described as well balanced. The sample tested had no audible microphonics and an average background noise level. Harmonic content was rich, lending that pleasant swirl and sustain that guitar players crave."
Note: Occasionally Shuguang sends tubes that are not printed with logos and part numbers. However, all are the same construction.

Shuguang EL34-B Excellence !
by cor
Hi Folks...I'm a 50 year + experienced, relentless audiophile that has never allowed any of the "so called amazing sonic revelations introduced to lure young audiophile newbies with Outlandish marketing strategies. SAD! My extensive years of experience in the Real world of reproducing music, AND NOT JUST trying to emulate music with all of the evolving crap that has flooded our market. Conclusion: DIGITAL= ONLY SOUND ANALOG=TOTAL HONESTY TO THE ACTUAL MUSICAL PERFORMANCE....More years and the countless thousands of hours perfecting my reference all tube, analog (vinyl) playback system...Hundreds of tube changes and evaluations in my power amp......SURPRISE TO ALL.....The new SHUGUANG EL34 B tubes win out hands down as the best musical sonic performer out of ALL others. OH...Evidence Defeats Doubt .......Fellow audiophiles agree, as well....blown away how awesome my system sounds with them.
Great tube Great pice
by Nedou812
I bought two matched quads for my Landry LS100G3, these are the tubes the builder Bill Landry uses for his amps. 2 1/2 years on the first quad with no issues, and they sound great. I am not a touring musician and probably only average 2-3 hours per week on on my amp, but I do play out occasionally and haul my amp to practices and play outdoor, back yard parties etc and these tubes have been reliable.
Marshall Power Amp...
by Travis
If you have a Marshall Monoblock 9005, these are the tubes to have. I have used JJ, Mullards,EH and Sovtek. Sonically with the 12AX7B these tubes are night and day over others. EH 6CA7 comes a close second. These bring these Power Amps to life. Solid bottom end, clear midrange and a nice top end. For metal its almost like having a tight boost with a bit of compression pushing your pre amp. I love these tubes ,No issues with reliability after a year of hard use...There is a considerable sonic difference...
Awesome Value
by Karl
These tubes are awesome. I've been switching tubes on my Musical Paradise MP-301 to see which are the best, and these might be it. Sound as good as my Fender 6L6, a little bit rounder and less clean. It sounds better than the Electro-Harmonix Electro-Harmonix 6CA7 (alternative EL-34 tube), which has more highs, but they are thin and make this tube ultimately sound better and sweeter to the ear. The Shuguang KT88-98 sounds about the same as this but doesn't distort when you turn it up, I actually prefer the distortion of the EL34 though.
Good all around EL34
by Derek Licon
Warm, chimey tone and tons of midrange heaviness that I love. I would buy these again and for the price they are great. JCM 2000 DSL 100. They also sound killer in a Bugera 333XL. I much prefer these over any 6L6. I think these are more bright sounding than JJ EL34 which I don't care for dark sounding anything so these were awesome.
