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:

  • Nicer tone
  • New texture
  • More open, perfect speaker to speaker side to side sound stage
  • A bit more separation of everything, all singers and instruments
  • A bit more layering now (and this is my SS amp, not my tube amps)
  • Other tracks, Nils or Stevie Ray, Guitars sound more authentic

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. yes

 

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. .

@decooney thanks for sharing.  Nothing to do with this thread but after reading through the previous (lengthly) thread you mentioned with the Psvane Rep. it prompted me to try some Art Series 12au7.  They were purchased through Amazon from a seller out of China.  I was looking for something warmer than their current Horizon Series, to switch out some of my NOS tubes that I’d like to preserve.  Long story short the tubes were noisy out of the box and I sent them back.  They’re sending a replacement set so we’ll have to see how the next set works out but I’m not optimistic. I should have thought through the purchase before making it since the pair I purchased was priced below market.  Quite frankly it seems that some overseas sellers maybe getting rid of Art Series rejects now that Psvane is pushing the Horizon Series.  Strangely enough it appears that Amazon has also since removed this particular seller.

To @marco1 was it the actual psvane co as the seller on Amazon? I spoke with them directly about this purchase vehicle too.   Apparently this was supposed to be their US outlet to buy from Amazon direct for PSVANE. Hmmm. Thanks for the note, I was gonna order two 12a..7 pairs too, Art Series, and I’m going to hold off until you report back on how this works out for you.

@decooney no these did not come from the Psvane factory store.  I believe the reseller on Amazon was Hi Spot or something similar.  It’s a Chinese reseller.  Replacements are due to arrive next month, but maybe they’ll arrive early like the first set did. They’re shipped from China but the return address is Portland OR.  Strange. I’ll report back once I listen to them.
