A: Congratulations for getting new tubes for your precious tube amp. Chances are either your stock tubes are getting aged, or you are about to experiment some different tubes hopefully to improve the system sound to the better. Either way, it is a fun and exciting experience.
Please follow the steps below to change your tubes:
Step 1.: Confirm that your amp is working fine.
Sometimes you come to the point to buy new tubes because the amp somehow isn’t working properly. The issue could be the tubes currently in the amp are getting too aged; it could also be that the amp needs a re-conditioning in case resistor / capacitor are out of spec from aging. This is a very technical process – if you are not sure and cannot make an educated assessment from experience, talk with a tube amp service technician.
Step 2: Remove old tubes from the amplifier. Read more...
Feedback received via email from Ricky B.:
“The CV 181-TII aka 6SN7 is a remarkable tube. I will standardize my amps around its new standard of excellence.
Super punchy, dynamic, smooth and highly detailed in a non analytical way. Very beautiful tone and body.
And they have 2 hours of break-in!!!
Thanks for freeing me from the over priced and questionable sonic integrity NOS nonsense.”
Feedback from customer Charlie V. via email:
“The difference between the Psvane (845) TII tubes and the stock tubes are like night and day on steroids. I am glad I re-tubed the amp and pre-amp all at the same time. What a marvelous difference. The air, sparkle, tonality of the music as well as the sounds of the instruments are stunning in the most enjoyable way. I could not imagine better sound and enjoyment. I could and am listening for hours at a time.
The transaction could not have been more professionally handled. I could not have had better results if you had a shop down the street.
Top notch in every way.
My amps are Cary Audio 805 AE
My pre amp is Cary Audio SLP-05″

Feedback received via email from Steve D.:
“Are those stupid Psvane 12AX7 T-II’s you guys sold me ever good! Instead of doing the standard PC audiophile “audition report” routine, permit me to be real. When I got into audio in a serious (i.e., a spiritual) way around 1999/2000, I found Arthur Salvatore’s new (back then) website (high-endaudio.com), and I have been a convert to low-level information retrieval ever since. My system is very biased towards this. I use a Jean Nantais Classic Lenco TT, with upgrades, which leads my vinyl front end (history will judge him as the Stradivarius of turntables, no exaggeration). George Wright’s (RIP) gem of a 12AX7 phono pre. Large double c-core passive TVC line stage. DIY crossover less full range speakers, 97 db/w/m.
My system won’t make the front of any audio mag, but it is very revealing. My initial impressions of the Psvane tubes in the Wright phono were: mids opened up first, dramatic increase in sound stage depth (plus other improvements); then same for bass; highs were the last to develop; getting better with every album.

Feedback received from Stephen D. via email:
“The Psvane (12AX7-TII) were obviously better right out of the box. Most importantly, I was hearing nuances that I hadn’t heard before. Better low-level information retrieval, which is the most critical sonic parameter, IMO. On Art Blakey / Jazz Messangers Three Blind Mice, the lead trumpet was more forward towards the mic, both spatially and sonically (in terms of amplitude – I’m still digesting this one, very different presentation). The music had all around better organization / less homogenized. Tone was excellent. Also listened to reissue of Joni Mitchell’s Ladies of the Canyon and Clapton’s Unplugged, which were better than I had previously heard them.
The frequency extremes are slower than the mids to open up, but I only have 2.5 albums worth of listening, so far. My initial impression are that these T-IIs are an excellent choice in the phono preamp application in terms of sonics, and thus they offer good value. I’m looking forward to further re-visiting the mainstays of my vinyl collection to hear what I’ve been missing.”
The newly launched Psvane KT88-UK and 6SN7-UK are filling the gap on the market for affordability and performance. Presenting a warm relaxed ‘British’ tube sound, these UK series will give you an excellent option when you consider to swap out your old tired generic tubes come from your amp manufacturer.
In response to strong demand for high output power tubes, we now carry Tung-Sol KT120 and KT150 tubes in matched quad. Matching service is provided by the Tung-Sol USA distributor and we ship from Canada to buyers worldwide.

Feedback received from Peter R. in Australia on WE300B Replica:
“I’ve just loaded up my Shindo Concertino with a new pair of Psvane 300B WE Replica’s from Grant Fidelity and was totally surprised at what I heard – straight out the box! It made me realize that these valves are a cut above.
I can’t compare them to original or re-issue WE’s, so these comments are more a comparison with brands such as Full Music and Golden Dragon – and over 50 years of listening to valve amps.
At this very early stage there seems more of everything. The sound is sweeter and deeper and very musical. These Psvane’s are certainly in a different league to others I’ve heard in the 300b territory.
Maybe calling them WE Replica’s might encourage some skeptical reviews, but that aside they are front-runners in their own right and they give me some insight into why we hear so much about the legendry originals.
I’ll come back in a few weeks with an update.”

Update – April 12th, 2014: In addition to KT88-Z and CV181-Z, we are adding back in 6CA7-Z model of Shuguang Treasure black bottle tubes now (April 2014) with our newly formed quality control collaboration with Shuguang tube factory.
Grant Fidelity discontinued our offering the Treasure tubes in 2011 as the original ‘Treasure tube’ design team left Shuguang to form their own company ‘Psvane Audio’ and offer tubes under ‘Psvane’ brand. From 2011 to now, Shuguang has restructured its design team but the Treasure tubes have been sold through various channels with no clear quality indication. Grant Fidelity now has formed special collaboration with the Shuguang quality control team to ‘select, screen and supply’ tubes that Grant Fidelity deem to pass our quality requirement to meet customers’ needs for ‘once gone back, never look back’. All our ‘Select’ quality tubes have print on the tubes ‘Select by GF-LJX’ with anti-counterfeit label on the base. Interested in ordering yours? Click here.
