The Shuguang EL34-B 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.

Risky!

The JJ EL34 is way better, the Chinese tubes are unreliable, 2 failures already, smoked a socket, and cost me some cash, the Chinese make great preamp tubes the Shuguang 12AX7A tubes scream and are cheap.







Note from thetubestore: You may have had some bad luck with this tube. Our data indicates the failure rate is within 0.04% of the average for all EL34 brands.

Another Failure

I have no idea how long EL34s are supposed to last, but one of my Shuguangs just bit the dust after about 18 months of daily use. They do sound really nice until they fail, but I am glad I had some E-H EL34s around to pop in my amp.







Note from thetubestore.com: 18 months of daily usage (estimated 1500 to 2000 hours) would not qualify as a premature failure. This would be a fairly typical lifespan.

So far so good!

Replaced both power tubes in my Guytron GT 40. Biased it properly and it is back to its sweet shimmery self. I will report back if other than satisfied later on. This is a heavy combo amp that roll around on a dolly, so the tubes get vibrational abuse.

Sounds great and reliable

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...

Reliable and hard working tubes

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.
