PSVANE Discussion & Impressions Thread

    I too had reliability problems with some 12ax7 Psvanne tubes, which failed quickly, several years ago, so I swore off them, but I might try an improved design.

  I could use “phono quality” 12ax7’s, for a phono preamp.  The only way I know to identify sufficiently quiet tubes is via testing; only a relatively small percentage of any manufacturer’s tubes are quiet enough for a phono preamp.  Will Psvanne offer anything like that?

 I could not find any kt-150 Psvanne tubes on Amazon.

it is nice to see a manufacturer be proactive about these things, and provide a real contact.  Thank you, @alightronics, for the info you are providing.

@alightronics  real fast youre sending out bad tubes with this horizon series. from a friend, 

"Ordered a pair of these via Amazon to try in my Decware SE34I.5 amp. Installed them turned on the amp. They biased up the same. About 20 seconds after turn on I hear a slight pop out of one speaker. Start the music playing and that speaker sounds muffled. Turn it off, let if cool a little, swap the two power tube position. Power it back on. Same result, the problem follows the tube. Will be sending this pair back to PSVANE via Amazon."

the reputation of psvane is the tubes sound good but frequently go bad in no time flat.  was hoping youd correct this with the horizon. 

in addtion, your official seler on ebay GD parts, ripped me off. i bought the new TIII art series on ali express as directed to by psvane, and as i purchased them the seller GD parts kept increasing the price. the seller promised theyd fix the price as soon as i place my order, so i did, and they refuse to adust to the correct price. 

you need to fix these things right now. 

I purchased both four Horizon KT88 tubes and a pair of the Horizon 6SL7's. The 6sl7's are running over 25 degrees cooler than the KT88's and not even close to being warm/hot like any other tubes I've used. Is this normal?

@alightronics its a surprise to see a tube manufacturer drop in on this forum. I'm a long time PSVANE tube user since the early Shuguang and TJ Full Music related tooling buyout days. Never tried Art Series, noting newer versions coming about.

How long are you planning to stay engaged on this forum (like this) about product, defect, and warranty support related questions?
