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.

Marshall 9005 Monoblock Shuguang EL34-B
by Travis
I have used all the popular brands of tubes over the years, some seem to sound better in specific amps. The Marshall 9005 Monoblock Power Amp originally came with Sovtek EL34G tubes. These Amps were noted to have bias supply problems. Biased hot at 47ma as well. Once sorted these Amps are Ultra Reliable and will run 4 4/12 cabinets. I recently tried a set of Shuguang EL34B tubes and I would have to say sonicly it now sounds better than my later gold face 50/50 monoblock. Sounds like it has a boost pedal in front of it. Cleans are amazing and is a gain monster. Amp used to have a pronounced amount of hum with and is now almost dead silent. Wished I had tried these tubes a lot sooner.
Maybe i shouldn't be so shocked.....

After I blew a Mullard reissue in my amp I had a few of these kicking around and decided to try them out. Originally, these tubes came stock in a hifi amp i bought off ebay. As far as I'm concerned, they should have come stock in my guitar amp. Smooth and balanced. Balanced seems to be the key to these tubes. Great response across the amps freq. spectrum. Almost like running a mild compression pedal out front. I'm running a Marshall 1987x clone from Ceriatone (68 schematic) and these tubes fit this amp pretty darn well. If there was ever a good reason for blowing a tube, this might be it!
Another Great EL-34 Tube..
by Paul Roy
To my ears, this tube has the sound and feel of EL34 tubes from an earlier era. Like the Tungsol EL34B, it's tone is authentic 'EL34' sounding. While it's low end response is not 'quite' as strong as the Tung-Sol EL34B, it's more then adequate, and decently balanced. It also represents a great value. For the money, you simply cannot buy a better sounding tube.. I love these tubes!
Reliable and hard working tubes
by Umberto Smith
I suppose I hold these in higher regard than the SED tubes because they lasted longer and did not have failures.
I think if you'd like honest tube life and don't want to spend more for boutique labels and sonic characters that may or may not exist, this is the tube for you.
Sounds great and reliable
by Denny L
Sometimes the fault may lie elsewhere. My AE SixPacs came stock with the Ruby EL34BSTR (same tube). Out of the box, fuses were popping, and the bias strayed all over the place in one of the amps. I thought it was the power tubes but was advised to swap in a new current source EL84 tube. Problem solved! When the time came I've since bought another set. In the SixPacs these Shuguangs have been reliable and sound just like reported in the review on this site - balanced top to bottom, with a nice shimmery top end. For the price, they're hard to beat. Dennis Had may have been on to something...
