I recently purchased some Psvane 845T mk. II tubes from Grant Fidelity. Both tubes bias correctly and keep the bias. But one of the tubes concerns me as there is one of the internal wires that seems to turn red hot once the tube is turned on. The other thing is that the silver flash on the inside seems a bit lighter/whiter than the other. The outside of the silver flash is fine and there is no lightening of the silver. Grant Fidelity assures me these are just cosmetic issues, but I wanted to ask you guys if that is actually the case.
I've attached 3 photos. One showing the red hot wire, one showing the lighter silver flash and one showing the darker flash of the other tube.

Rachel, at GF, is great to work with. You should not have a problem getting replacements. My Psvane's work perfectly..
As far as I'm concerned, she's the best.
Agree 100%..
Just about the only place I'd look to for Chinese made tubes.
Problem is, she is giving me a hard time, telling me that the glowing red wire is just cosmetic and that the tube is perfectly fine. Also, to send it back, I'll have to pay shipping to Canada which is about $40. I already had to send the first pair they sent me back because there was a bunch of white flakes stuck to the inside of the tube. That cost me $40 to ship. So if I want a replacement for a non-defective pair, I'll have to shell out $40 + the $40 I paid for the first return + $400 I paid for the tubes originally. So basically, I'm paying almost $500 for a $400 pair of tubes.
Hi Eric,
Please understand that you are asking me to replace something that we have no means to measure and no means to predict in the next pairs. So I have offered you a full refund very promptly, as I don't see a way to offer you next pair without possible this issue, OR another issue that is not factual failure - these are called 'your concerns' in your email. They cannot be measured in a tube testing equipment.
We use Amplitrex AT1000 with 845 adapter to double test 845 tubes. All tube testers on the market can only go up to 500V for testing, but in real amps, 845 has nearly 1000v on them. We cannot duplicate this voltage condition to reproduce what you have concerned of, which some suspect it will lead to unknown consequence. Such a suspect is fair enough and I have authorized you to return to be refunded in full so you have a peace of mind.
Your comment of 'bunch of white flakes' in the first pair sent to you is exaggerating. I looked at your returned one and only one piece of material residue is identified. And I have given you factory's explanation and so far that tube isn't tested with any defects with Amplitrex and work just fine in my test amp, but your 'concern' had lead to your wish to return them in the first place, and we granted the return instantly.
You paid to return due to your concerns, we paid to replace it under our warranty even it is not a warrant-able issue according to factory . Fair dealing, right?
This pair is 2nd round out of your concern. I do not wish to continue sending you 'functioning' tubes but you keep having concerns and we just make more business for carriers only but both sides are at loss.
We have NEVER stepped away from our warranty - if a tube fails as a matter of fact, we replace no problem at all. This is a FACT.
To this date, there is no factual tube failure on either pairs. Both cases are 'your concerns'.
To avoid we keep shipping, and your concerns keep growing, and to where we are now we as vendor in a loss with this sale, and so you as buyer in a loss with repetitive return shipping, I say we close the transaction - you return it and we refund your order in full. Does this make sense to you?
If your goal is to get a working pair, yours is working and we have a warranty in place to replace it when it stopped working. But I don't have a warranty policy to stop you from having concerns. This is my bottom line.
Thanks for your understanding.
Regards,
Rachel @ Grant Fidelity
Grant Fidelity - Psvane Tubes
With what seems to be a very problematic tube.
Keep communications calm, short, reasonable and open. If it's properly functional then move on with it. Maybe just ask if it blows in one year to replace it?????
Best of luck to BOTH of you

The glowing wire he is describing is a factory defect and should be replaced by you at no cost to the buyer, including return shipping. Your guarantee is very conditional at best if you take the stand you seem to be taking.

May have NOTHING to do with the tube in question.
Rachel has replaced the tubes once already for 'concerns' of what is likely an imagined problem with a bit of loose material or 'white flakes' inside a tube (or tubes?) and has agreed to a complete refund now that the customer has additional 'concerns' with a glowing wire.
The OP should take her generous offer and STFU!
I've done business with Grant, as have many folks I know, and they are one of the few places I would go to for Chinese tube for the very reasons we have witnessed in the thread.
I will continue to buy from Grant without reservation in the future.
First of all, you have a lot of nerve telling me to STFU. You don't know me. Where do you get off with your pompous attitude?
So, if you saw a giant white flake stuck the inside of a brand new $400 tube, you'd just think it's imaginary? I searched the web and everyone says white flakes inside tubes are not good. So, Grant Fidelity agreed to replace them and I forked out the $40 to send the first set back to Canada.
Then I received the second set and noticed the glowing red hot wire and it concerned me. But I suppose that's imaginary as well. Is it so wrong for me to have asked for another replacement? Would you have just said, eh, a wire that's not supposed to be glowing red is glowing red, but oh well, they already had to replace it once so I don't want to bother them again? It it was a $50 tube, sure, I guess I'd suck it up. But I paid $400 and then another $40 to send back the original pair.
As mentioned I don't want a refund, just a properly functioning set of tubes. And Grant Fidelity won't honor that, saying that the glowing wire is just cosmetic and doesn't fit their warranty for replacement.
Even after I agreed to pay for this set to be shipped back yet again, they still wouldn't send me a new set. They would only send me back the first set they sent me with the flake.
This morning I received an email stating that now all my correspondence would now not be responded to and just archived.
I responded to that by saying fine, I'll take the original set back, thinking the white flake must be less dangerous than the glowing wire.
I'll give until tomorrow to respond to my offer and if they do not, I will escalate.
And don't tell me to not mention the company's name. In this day and age, when you're dealing with a difficult vendor, sometimes the only way to get an issue resolved is to use social media. Had they just agreed to replace the glowing tube up front, I would have never even wrote the original post. It was only after they continued to deny that a glowing red wire was not a defect, that I was left with no choice.
So, please, step down from your high horse and watch what you say to people you don't even know.
I dealt with Rachel and Ian quite happily and the last word to describe these dealings is "difficult."
Somehow I managed to use 845s I've bought from them without even bothering to inspect their innards. Fact is, I can'r remember ever looking inside any tube I've bought from ANYONE. My bad.
I do think it's a defect, but the company offered a refund in full. The OP should have shipped the tubes back and left the company name out of the discussion. I understand his frustration, but I know of no audio retailers who can test high power transmitting tubes under actual operating conditions. Most can't even test a 6L6. As bad as that can sometimes be when purchasing Western tubes, purchasers of Chinese tubes must be willing to accept additional compromises and to expect more frequent defects, both being quality issues generally reflected in the lower cost of Chinese products. Above all, it makes no sense to blame the retailer for any of this.

You don't need to measure a glowing red hot wire. The wire should not be glowing red and is therefore a defect.
IF you are willing to pay to return it?
Or am I missing something?
They are saying that they'll just give me a refund because they say there is nothing wrong with the tubes I have now, hence no warranty replacement. I just want a working set of tubes and don't want to keep paying $40 to ship them back the defective tubes they keep sending me.
I'd be careful and contact Jim McShane. On the other hand, I have had good luck with Shuguang, but no 845 tubes in my system.
If GF does not provide a replacement....I'd be saying so long GF.

I would demand a replacement tube. That glowing wire is definitely a flaw with unknown consequences. It is not just a cosmetic problem.

"one of the internal wires that seems to turn red hot once the tube is turned on."
That would be a reject if it were US made.

Too bad there are no US companies that make any tubes let alone 845s. Beggars can't be choosers.
Isn't there any NOS left anywhere? The retailer may be in Canada, but you're having to shoulder the burden to replace tubes that never should have been shipped out of Asia. I think you should get your money back and do business somewhere else.

Unfortunately, NOS 845 tubes are EXTREMELY expensive. I've seen some RCA's that are going for $1,500 EACH!
I don't normally keep track of 845 pricing, but I see you're right about this. They've become much more expensive than even just a couple years ago. It doesn't seem as though you have many choices in this matter. I have to say, if I were faced with the idea of a system that could only take Chinese tubes or a $2,000-3,000 pair of NOS, I'd sell it. Alternately, I might convert to 211 or GM70, but only if the amplifier(s) were loaded with high quality Western iron. Chinese amps wouldn't be worth the trouble. In that case, I'd try to get one pair of working tubes somehow, then trade up.
--------------------------

I remember at one point I unloaded all the gear that had unobtainable parts if it needed repairs.
If I had that amp I would unload it like toxic waste or change it up to a more available tube.

Made me laugh!
