Has anyone purchased/used the new Shuguang "WE Replica" 845 tube? To me it looks like an attempt to copy a United 845W, and does not look anything like the well-reviewed Psvane WE845.
Thank you for your replies. I have ASL 1006(845) amps, and interested in trying some 845's other than the stock Valve Art.

Agree, this is not the same tube as Psvane WE845 and does indeed look like a copy of one version of the United 845. It's also somewhat cheaper than Psvane.

I suspect it will not sound near as good as Psvane, which is the best sounding example of it's type IME and by a decent margin. Would also love to hear from someone who has directly compared though.

There isn't much info on what Shuguang is doing to counter the separation of the Psvane folks or even what is going on with Psvane. The Shuguang WE845 may be a totally different and new tube.

While the plate construction is similar between the two the top bracing appears to be a copy of the United. FWIW, United made versions of tube with and without this brace and many believe it was detrimental to sound, which makes me wary about Shuguang's WE845 compared to Psvane's.

All I can say is that the Psvane is so good compared to everything I've tried that I've not even contemplated changing since. The only word of warning is not to run the Psvane much above 80mA for best sound (IME).

As Jim McShane says, you can't tell much about a tube by looking at. ;-) I think the Psvane & Shuguang tubes, in general, are excellent.

I haven't tried these but they do look interesting, and the price seems reasonable. Let us know if you try them out.

The 'top-plug' design does come from United, indeed, though perhaps a bit less elegantly implemented than the United solution. These look like a new plate/support design, taking ideas from United, Sylvania (the + shaped top ceramic) and GE (the vertical wire supports).

Psvane: these are made under contract by Shuguang, aren't they? Psvane is just a branding/marketeering/reseller/testing group, not a manufacturer, from my understanding. It's good to know they sound good, but I haven't gotten around to trying them yet. They are a bit pricey for new-production, for my taste...

Hey Ed,

Not sure about the Psvane story and tend to think you are correct.

Of recent production 845s I know that you liked the sound of the 845M and using this as a reference I agree that their successor the "W" (I think) did not sound as good but still a cut above the standard 845B IMO.

The Psvane T series was a definite step up from the W but the WE845 was better again in every respect, seriously worth the money IMO and those I know who have tried them agree.

But I had reservations at first. While the sound was balanced, nuanced, extended and had the hallmarks of a great tube there were signs of congestion under certain circumstances that took a while to figure out. In fact I was close to returning the tubes but decided to try lower current in the faint hope that they didn't like 85mA. Previous experience gave me the idea.

Well, I honestly did not expect such a transformation. I couldn't believe what I was hearing, just clean, balanced 3 dimensional, undistorted and dynamic sound. No upper mid-range glare or top end edge despite greater detail, particularly low level.

The proviso is that 80mA (at 1KV) is nearing their limit, 85mA is too much.

Tried a set in my brother's system and exactly the same result so he bought a pair and loves them too. We have both been running these for some time now and have not had any desire to even try anything else since.

I've been impressed with Psvane in general but if you have a chance to try WE845s you will not be disappointed. I know you've tried just about everything in 845 so I'd really love your opinion should you have the opportunity.

Cheers,
Naz

Naz, thanks for the details on that. I will post if/when I get an opportunity to try out the WE845s. They sound like interesting tubes, no doubt.

thanks

Before I say anything else I should make it know that I own a quad of Psvane WE845 tubes I use in a Mastersound Reference 845, SET amp and I absolutely love their "sound."

That said, there's a very real possibility that the Shuguang WE845 sounds better than the Psvane WE845 tubes do! Why do I say that?

Well, it turns out that Psvane voiced their WE845 tubes to sound like the original WE284a tubes. But Shuguang voiced their WE845 tubes to sound like the later, and better-sounding, WE284d tubes!

So it's quite possible the Shuguang WE845 tubes sound better than the Psvane WE845 tubes do. A comparison of these two tubes is definitely something that should be done...
