PSVANE Mfg Co replaced my older 6SN7 CV-181 TII tubes
Sharing - in case this might help others. This came out of the blue unexpectedly.
Over the holidays I had written PSVANE Co Mfg asking why my older TJ Full Music 6SN7s simply sounded better than my 3yr old PSVANE CV-181 TII tubes I only used 1yr. These TIIs had a mfg date of Oct 2021. Used them some, they got dull. Had been just sitting there in a fancy box and I happened to mention it vaguely over one email that was more about the new line of tubes and wondering about change overall with the new series of tubes. I was not there for any other reason.
Also confirmed that PSVANE did in fact buy tooling and some of the smaller tubes business from TJFM after the father passed on. Another reason I was comparing.

I was #1 asking if any of the TJFM tooling and offerings had made its way into the new lines of PSVANE had been offering in 2024, including ArtSeries, Horizon lines.
#2 reason was to get an idea of what may have changed since coming out of the pandemic and/if there were updates on the overall design, quality, testing, QA for any of the 6SN7 CV-181 types of tubes, PSVANE, other lines.

Long story, I get this reply back a day or so later from someone there [not identifying a name, just an email distro list] asking me to send photos of the tubes, test tags, boxes etc. Back and forth a few times over email with good English and extra help coming in - nice, interesting.
I had also recalled recently seeing psvane tubes showing up here as.a member on Agon and that time was short lived before being removed by Agon admins or someone. It was clear to me they were trying to assess their position, customers, and any feedback they could get here on Audiogon. So, I gave it directly over email. Honestly,still hung up on why my older TJFM tubes sounded better :)

RESPONSE:
PSVANE immediately came back and told me there were known "quality assurance issues" during that Oct 2021 period and they "would happily replace the tubes with new ones", shipped to me "free of charge", direct from the factory. Also expressing how those matters have since been resolved and did not want unhappy customers.
I agreed to their policy to physically "break my tubes, smash the glass, photograph them, send them photos". This is so bad tubes don’t end up back on the market being resold and causing further complaints no longer the case with new versions.

Tubes arrived in 17 days after they agreed to pack well and ship. They are the same TIIs with a different looking "T Series" label on the box outside for T-Series.
From the outside, same shape, size, same gray coating, bigger than my TJ Full Music as before. These 2025 tubes look close to the 2021 version outside.

SOUND, out of the box:
First test they were a little veiled over for the first 1-20 minutes. At hours 1-4 increasingly opening up, texture and sound stage all coming in at once - with definite separation, not blurred together at all. Pretty neat actually.
6SN7 tube preamp, 50w Class A solid state amp for the first try. Tube amps later.
Track:"In my secret life" by Leonard Cohen
Hearing his voice direct at the center, and female singers coming out of Right & Left channel at the speakers from both sides - all at the same time but with real separation. Some of my other 6SN7s can co-mingle the sound just a little bit.

Changes:
Why Share:
I replied to the person of authority there who replaced these tubes for me that I’d make a post of exactly what resulted and that I’d tell it straight as I hear it good or bad starting out. Maybe some updates later over time as tbd.
-----
Next:
I’ll leave these full replacements in my preamp for at least 90 days or unless something changes.
-----
Summary:
Glad I gave these newer 2025 PSVANE a 2nd chance vs buying others like the Horizon or just staying with my older TJFM still lasting well, gonna store those.
We’ll see how this goes and if they last. Hope to keep them in play, they sound very nice right now. 
Not sure if this helps anyone or not but some times it might be worth giving things a 2nd try maybe, and particularly so when the MFG wants to help make good on it.
Enjoying what Im hearing right now. It’s causing me to keep my SS amp in play for longer too, no joke the guitar tone, texture, and spatial sound is extra nice now fwiw. .
To @milpai thanks for the update and sharing your story too. You are now in the same position as me, waiting about your replacements, "if they will last". The only added context or hope I have is how this unnamed leader informed me they "do" acknowledge having quality" issues with tubes made in the 2021 time period my last tubes were made. Did you happen to take a photo or still have the test cards for your prior tubes that went bad prematurely - did they show the month & year manufactured? |
@marco1 , If you have to buy the ART series, you should use Vivatubes. Assuming that you are based in the US. But for such a delay, Amazon let’s you cancel the order. |
@milpai i’m in the US but It’s already been shipped and supposedly on the way. So they will not allow me to cancel on line. Maybe if I spoke to customer service. But It’s really not that big a deal. I’ve got plenty of tubes. I can wait. I saw that Viva sells the ART series. At the time Amazon’s price was about $30 cheaper for the pair. Since they’ve raised the price to more than Viva. This may very well be the last time I buy Psvane although the Horizon series intrigues me. Live and learn 🙃. |
@milpai @marco1 this unnamed leader person at PSVANE Co shared over email that Amazon is the primary method they use to sell tubes in the USA now, even ahead of Viva. We got into a sidebar discussion about me having to return a pair of GL tubes that were very poorly packed inside the small boxes, one was DOA, and they mentioned having a shipping/packing issue with Viva and returned tubes too. I myself have not had that issue previously with Viva until this last time with my GL tubes fwiw. Thankfully Viva refunded me. Yes, I took extra time to write notes back to Viva about how they need to FIX their recent light packing / less protective and boxing issue. The dam GL tubes had no protection inside the boxes, semi-rattling and sloshing around inside the little tube boxes, totally avoidable. Maybe an isolated issues with an employere over holidays, I dont know. Just guessing. PSVANE did call this out about them and how we got onto the Amazon order channel. Same BS happened with TJ Full Music a few years back. They would ship 100 tube containers to the US ditstributors safely, they would arrive fine, then get stripped down and shipped out to clients in pairs in a much less protected way. Took TJFM about two years to figure out what happened there and why. I ordered tubes back then from an overseas distributor, and the tubes always arrived super well packed and double-boxed too, with cotton inside the tube boxes internal/external for comparison. Let’s see what you get from Amazon now. We can compare. Ask: @marco1 when the PSVANE tubes arrive from Amazon can you take a few photos of the outside of the boxe(s), and the packing of tubes inside the tube boxes?
