Shuguang EL34 testimonials from around the Web, with acknowledgment and thanks...

“The sound is very clear with good dynamic range. Top end has nice extension but never bright, with great texture in the mids and bass.”



“I find the Shuguang EL34-B to be a very warm sounding tube with a magic midrange. Highs are excellent, but not to sharp. The bass is there but also very well controlled. After about 100 hours they really come alive. They are much louder and CLEARER then the other tubes I've tried. That's the true magic of this tube, the clarity, they really help my Triangle Celius 202 speakers image very well. They also produce a very accurate and uncolored sound. For the money, I can't imagine they can be beat.”



''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''



“.... if I had to pick one for best tone it’d be the Shuguang EL34-B….Once I can convince a customer to try the EL34-B, they almost always come back for more. The Shuguang folks make excellent glass….”



“The Shuguang 12AX7 tubes are great reliable, good gain and have a big sound, nice mids and lows as well.”



“I am a big time Shuguang convert. I prefer them to most 12AX7s that I have tried and for the price I don't think you can beat them.”

If you are ordering from more than one of our listings, note that we can offer you reduced combined shipping ONLY if you use "Buy it now" on all items then request a total from seller BEFORE making payment. We will then send you a combined shipping eBay invoice to pay. This is NOT possible if you have already paid for any of the items you are ordering.

Customers in Italy please note that due to the high number of orders that vanish and never arrive whilst in the hands of the Italian postal system, we will only send orders under £22 in value to Italy via standard untracked airmail. If your items total more than £22, please arrange to pay for tracked and signed shipping so that your order may be shipped safely and securely. If this option is not offered in the listing, please use the following listing to pay the extra cost of this.
Tracked & Signed supplemental charge to Italy 

Also note that orders sent to Italy may take MUCH longer than eBays estimate to be delivered and, whilst some orders do arrive within a week or two, many orders sent to Italy are not delivered for three or perhaps even four weeks! This is entirely outside our control, as we ship within two working days and once your order is in the hands of Poste Italiane, there is nothing we can do to get it to you any faster. 

Please DO NOT send messages with the title "Item not received" as these open complaint cases against us and damage our seller rating! Instead please use the general "Other" heading to ask about your delivery if several weeks have passed.

Lastly, all please note that when eBay asks you "Did the item arrive on or before" their estimated delivery date, it also damages our seller rating if you answer "No", so bear in mind that we always ship within two working days, so if you answer "No" because your local postal service (especially in Italy!) has taken weeks to deliver, you are punishing us, not them!

Thank you all for your kind consideration of the above and remember that we will always do our very best to sort out any problems or questions you may have related to your order if you contact us using the "Contact Seller" and (if the choice is given) "Other" ask a question of seller options.
