PSVANE Discussion & Impressions Thread

Ha, Mglik!  

Maurice is rolling over in his grave!

I am on my 3rd quad of EL34PH tubes being run in my Cary SLI-50.

Fantastic sounding tube. While having a different presentation than the Winged-C’s, they are very similar from a qualitative standpoint. The Winged-C’s have been some of the best sounding/performing tubes I have used in the amp. 

Love the EL34PH. Well balanced tube, with a great sense of space/air. Tight bass, textured mids and clean/extended highs.

I do have to complain about the longevity of these tubes, which quite frankly sucks. 

The first quad had issues w red plating after a couple of hundred hours. The dealer replaced them with a fresh quad after some back and forth. The second quad lasted a little longer, and one of the tubes red plated from that also. 
 

Ran some KT77’s for a while after that followed by some elcetrohome tubes (which did not deliver) so I ordered another quad of the EL34PH’s and I am hoping these prove to be a bit more reliable. If they are not, I will have to go back to the Winged-C’s which have sadly become rather expensive - but at least I know they last for a more reasonable amount of time.

@perkri Hi！We have just reviewed the after-sales data for this product and found very few issues. It is likely that there was a problem during the transportation of this batch. Regardless, if your product is still within the warranty period, we will assist you with the after-sales service.

I just bought a used PS Audio preamp that came with three pairs of PSVANE 12au7 Art series tubes. One pair was in the preamp and the other two pair were still in their boxes. All of the tubes were noisy and within a few weeks, 5 out of the six tubes started making clicking noises. There is nothing I can see happening and there I can see wrong with the tubes, but I know that doesn’t mean much.  Anyway, I bought a pair of Gold Lions and they have been working fine for almost four months now.

I had purchased several pairs of Psvane 12ax7-TII from Grant Fidelity with excellent results.

So much so when the Psvane 12ax7 art series came out I ordered 6 from Viva tubes. My preamp uses 4 and I ordered 2 extra. Within 6 months all of the tubes were unusable.
