Being that an authentic quad set of these tubes would sell for around $400 + with a US based dealer, and also considering the fact that PS-vane tubes are manufactured in China, and then noting that this is direct from Ali-express, this sure looks inviting to order knowing that if they are the real thing, and they are as they say, then this would be too good to pass up. If they are counterfeit, then just a complete waste of money.

This falls into the category of being "Too good to be true".

BUT, for a QUAD set of matched el34PH tubes from PS-vane at a markdown of 79 percent off ?????? I really have to wonder if this has any sense of legitimacy at all.

I am not sure about the quality either considering there is a mixed bag of reviews on these. There was a Decware amp owner who said that one popped immediately in his amp. He switched tubes and the other tube popped as well.  Not sure what that was all about, but that makes me really wary of buying these tubes.

So many people on other forums or who have left product reviews state how these are the best tubes available sound-wise. That is great, but if they don't stand up to the test of time, they are worthless to me no matter how good they sound.

I know there has been talk on this forum about these tubes in the recent past, with a mention of these tubes lasting over 800 hours without a hitch.

I can stand to lose $60.00 on a risk such as this, but if I paid $400 for a set of these and they had longevity issues, then I would be really upset to say the least.


So, if anyone cares to comment, what do you think about this offer?

Something tells me that I need to use strict judgement concerning this seller offer and be very cautious before even considering ordering this set.

The price is low enough, even direct from China, that suspicion raises a red flag.

If these ARE authentic, then this offer is too good to pass up.  I would love to try them out in the ToriiMK3 and see if they are what users say about them, hopefully in a positive aspect.

If you use these and have a great deal of time on them, I would like to hear about the results.

If anyone knows of deception here from this seller, then please inform me of it.

I really don't want to throw away money on a set of worthless tubes as that could go to a set of quality tubes from a reputable source.  I absolutely will NOT pay upwards of $400 to $500 for a set of these in the US. Completely unwarranted and not worth it.

So here are some images of the tubes for sale.  Tell me what you think about this.









My better judgement cautions me to leave this offer alone.  But I am considering the risk.

About the same price as Decware's el34 quad set. Probably safer purchase with Decware.

In my hot/cold experience with Psvane tubes I learned it best to deal directly with Psvane. I know they have quality control issues from first hand experience but when dealing direct they are very responsive on fixing issues.

Several times I purchased too good to be true items from Aliiexpress just to see what would happen.  One was a automatic litter box, another was a gas generator and in both cases the items never shipped, so 30 days goes by, item never ships, request a refund, get a refund.  

You just gave these people your money to use for 30 days.  It's a scam.

Dont forget that there are hobbyist and audio lovers that are as passionate about gear and music as us in China. Where do you think this sites favorite Lii speakers come from and a good portion of Decware tubes?

Ali isnt that bad. They are just like Amazon in that they oversee sales and have dispute teams in the same manor. Yes there are a lot of profit and sales driven vendors on Ali selling anything and everything.
There are also vendors selling high quality audio products that take audio seriously. You just have to spend time figuring out what stores to avoid.

I've purchased some great tubes off of Ali with no problems and some of the stores communicate very well. I see the stores come and go now with the tariff issue happening but there are still some honest vendors on there. One of the tube vendors I bought from who sold multiple brands informed me directly that they were no longer selling Psvane as the return rate do to QC was overwhelming. The Linlai and Shuguang tubes I bought from them were fine.

It took me a long time to trust and place an Ali order and the first thing I bought ( cheap $60 preamp ) was shipped with wrong country wall adapter but I was refunded as soon as ups accepted the return on my end. They didnt even wait to recieve it.

The only problem I had on Ali was from the actual official Psvane store and both the products and the refund process became a nightmare. It was confirmed by Psvane that it is indeed their official Ali store. Psvane also recommended dealing directly with them in future to avoid problems and insure I get the product I want. Psvane is very responsive when you email them directly.

Ive also purchased a lot of speaker, power and IC cables from Ali all very high qaulity and fast shipping to US.

The pricing , the discount coupons and shipping fees are all over the place and vary from store to store and can be confusing but I wouldnt rule purchasing from Ali out all together. Just be cautious.

Don't get me wrong, I realize that dealing with vendors anywhere in the world, and absolutely within the USA, or China, can carry a risky flag when doing business with them. Not all people are honest, but most are. It is getting stung by that dishonest group that really sets me off. It is a fact that one must use caution in every task or purchase. Ultimately, we are the ones making the decision, so in essence, we are solely responsible for the outcome. We are all aware of the bad guys out there. If we use an appropriate defense shield, they can't hurt us.

Regarding Ali-Express, hey, this network is just another version of Amazon, although regulated and controlled by a communist government.  This seems to be a good platform which I have dealt with many times in a satisfactory manner. I can tell you that there are a lot of bad products being sold on Amazon, so this applies everywhere there is commerce. I have not actually had a bad experience with the vendors in China. As a matter of fact, I have a very good opinion about their business practices.

It is the unfair trade practice that is destroying the US economy that I have a problem with. I do not have a problem paying extra to cover tariffs, as they are designed to make the lives of our children in the USA a better one in the future. If anyone fails to understand that, perhaps a bit more attention should have been paid while studying economics. I don't understand how anyone could graduate at a college level and argue the basis of solid economic factors, even at a high school level. Nobody seems to have an issue with the tariffs that Canada so aggressively imposes upon our goods shipped into their country. Of course, we are always the bad guy if we do the same.

Back in 1983, I spent a year living in South Korea very close to the DMZ where I have personally had great experience dealing with the Asian culture.  The same goes for my experience in Europe. I witnessed the events in Iceland which fueled the eventual destruction of the Berlin wall, as negotiations between Reagan and Gorbachev eased relations to end the cold war, and reunite Germany. I was stationed there when all of this was going down. The world has issues, that will never change, only the issues change.

And YES, why DO most products come from China today? Again, unless you have had your head buried in the sand over the last 30 years, then that reason should be obvious. Our own greed and political poison is the core aspect which fueled our declining system. We have always been the giant in industry for which much of the world depends upon. We gradually kept closing our factories and allowed our education system to fail miserably, while other countries advanced ahead of us (except in defense technology, and other technology relative to military use).

That is about to change. Some serious rearranging is required in order to alter the sick and dying methods which are inflicted upon our pathetic economic system today. If we don't wake up, there will be no turning back. I feel for anyone who doesn't clearly understand this fact.

As for the PSvane tubes, they seem to have a pretty bad reputation concerning quality control and unreliability, now don't they?  I would not brag too much about who uses these poor quality tubes. This is exactly what is wrong with products being sold to us today at over inflated prices. Corporate greed and the "dumbing" down of society....seems to work hand in hand.

I don't forget anything. I don't forget that guys like me vowed to put our lives in danger in order to keep America what it was meant to be when our forefathers wrote the Declaration of Independence.  Does anyone remember that?


The internet in general is the largest form of deception ever devised.  The world became a much smaller place once we all became connected with instantaneous communication.  Does anyone realize how the internet was developed and how it came into existence?

As with most high tech technology, the internet was funded and developed by the US military department of defense.

It was designed for the purpose of information sharing in the scientific research world.

The main focus was to provide a communication network which was decentralized during the Cold War for a safe and secure means of keeping things in real time, with security measures to keep information confidential. The major intention was to provide a secure system which could withstand a nuclear attack, so that communication would still be possible, regardless of the overall damage inflicted upon the network.


Great genius scientists such as Tesla, Einstein, and Wernher Von Braun were at the forefront of modern technology. Without the groundwork which they inspired the future, much of what we enjoy today would have potentially never existed, at least not for perhaps a century later.

The Department of Defense funds D.A.R.P.A. today as the leading source of technology within the defense sector, eventually bleeding out into the world of civilian (select) corporations such as Microsoft, Google, Boeing, Lockheed Martin, Intel, etc..... to carry out the transition under direct control of sensitive components which may or may not be classified by the US Government.

Today, we are under siege by the advancement of AI. It doesn't take a genius to predict the future of where this development is going. If you think that the advancement of AI is a good thing, think again!

In many ways, I feel the same way about the public having access to this world wide web of deception.

There is a reason why books and anything leading to the advancement of technology was held back in the dark ages by the religious sector. They foresaw the future, and tried to prevent the inevitable from happening.

We are merely fragile mortals who really don't control anything, although man's ego would dictate otherwise. We all pay for our failures as a society in the end. That end may be coming sooner than one can imagine.

How's that for some early Sunday morning doom and gloom!




On a brighter note for those more sensitive to bad news, get those audio systems warmed up and leave the world behind. You will have a much better day for it.
