We always aim for the BEST.
Some users have reported that they experienced Psvane KT88-TII series reliability issue in the past 3 months including tubes shorted unexpectedly within short period of usage.
Although all tubes from Grant Fidelity were tested multiple times before shipping, the reliability issue was caused by a minor structure problem that can only be identified when a tube is heated over extended period of time. To correct this issue and continue offering Grant Fidelity customers the highest possible quality tubes, we have returned all our stock acquired prior to April 15th back to factory for a new batch that has the issue addressed in production.
New stock of Psvane KT88-TII series GF Grade A tubes now are in stock and we will start shipping back orders and warranty replacement from our Hong Kong warehouse right away.
Thank you for all customers support to our continuous efforts in pursuing high quality products.

“There is no going back…”
Feedback received via email from customer Chris in Australia:
“Hi there, Rachel, just wanted to let you know that the tubes arrived in top condition on Friday 8th. I popped the 12AX7-T in first for a few hours and although it needed at least a couple of hours to get over the light bass and slight tonal greyness, the transparency of these Psvane tubes is wonderful! After 9-10 hours it simply becomes an essential addition to the TRI amp! There’s no going back after that.
To keep it simple, Rachel, I gingerly replaced the stock output tubes with the KT88-Ts and all went well and two days later everything seems fine, don’t know what happened all those weeks ago.

My amp uses many tubes in total – which one should I upgrade?
A: Answers to this question is related to your budget, as well your desire for the level of sound improvement.
The general rule of thumb is:
1) Upgrade the pre-amp tubes first. These are typically the smaller tubes at the front of an amplifier (power tubes are typically at back closer to power output transformers). A sound signal from your source component (such as CD player) is sent into the amp for amplification – preamp stage is first amplification stage so money spent on upgrading preamp stage tubes will give you great improvement. Garbage in, garbage out. If you don’t get great preamp signal, you won’t get great final output signal to speakers.
2) Once the signal being amplified at preamp stage, it is further amplified at the power tube stage. If your budget allows, get the power tubes upgrade to the extent that your wallet is happy and your ears are happy too. Most common power tubes are EL34, KT88, 300B and 845. The price for these tubes are in the same sequence from low to high.

I tested my new tube in my tester, it’s drifting. Is the tube bad?
A: No, not necessarily.
A tube tester uses a pre-built circuit to test a vacuum tube’s technical specs DURING THE TESTING PERIOD. Many factors come into play when the tester gives you a tube plate current result (in mA). This testing period typically last only a minute or two – some tester has pre-heat phase (such as Amplitrex has 60 seconds pre-heat on auto testing mode), others may not or the pre-heat period is too short to have the tubes emitting stable stream of electrons (current).
Tube is a live creature – when heated, it emits electrons and work in a circuit; when not heated enough, it will generate electrons but the quantity may fluctuate overtime then stabilize. A short testing in a tube tester will not definitely tell you if a tube is drifting (i.e. current keep changing) or not. Drifting is term used over extended period of usage time – not over a minute or two of testing in a tube tester, especially an old tube tester that hasn’t be calibrated for years with aged parts inside which could cause significant error in testing results generated.

Psvane KT88-TII: “sent goose bumps from my head to my toes”
Customer Jonathan M.’s feedback about Psvane KT88-TII tube upgrade from standard Shuguang KT88-98:
Hi Rachel,
WOW! That’s all I can say… Or, as John McEnroe used to say, “You cannot be serious”!
I have just finished listening to Supertramp’s Crime of the Century, and it is as if a veil has been lifted – I heard things I’d never before heard, but even better, the sound itself was so smooth and clean and tight and revealing and melodic and engaging… I have been listening to this album for 30 years and I feel like this was the first time I’d actually “heard” it.
The improvement over the stock tubes is quite amazing – sent goose bumps from my head to my toes!
So, thanks again for your help along the road to real high fidelity.
Regards,
J.

Psvane 12AU7-T (Grade A) vs NOS Telefunken 12AU7
Received via email by Thomas L.
“Dear Grant Fidelity,
I’m writing to let you know that I have received the PSVANE 12AU7-T Grade A tubes. I believe by now, a lot of people know that the PSVane T-tubes are good. But I’m not sure if any one of your customer have done a direct comparison to a brand new NOS tube. I’m comparing it to a Brand new NOS Telefunken 12AU7. I’m sure you probably have heard the following details many times, this may be just a reiteration of what all you existing customers are saying.
Just out of the box, the PSVane beats the Telefunken in EVERY WAY. Most significantly is the level of details and clarity, the Telefunken is no where close. This includes comparing with broken in Telefunken 12AU7. Equipments in the soundstage are spot on. String simply has more texture and reverb is more obvious. The Tube reveals so much more details but not bright at all. Soundstage depth and layering are much improved. All of these improvement are just with $99 USD. I spent roughly $230 on the set of NOS.”
