I have bought a number of Psvane tubes and TBH, I think your claim of matched tubes is a big disappointment. I just bought a pair of expensive ART series 6SL7-T3 for $220 which were supposedly matched and certified at 90mA. One tube measured 69/64 mA and the second tube measured 71/61 mA, a discrepancy of over 15% between triodes, not considered to be a matched tube by industry standards.
I also bought a quad of 6CA7-T3 ART tubes, certified at 35 mA and they ranged between 31-36 mA. I have two quads of Psvane EL34PH and one quad is rated at 29 mA and they ranged between 24-31 mA and the second measured decently.
When I purchased quads of Gold Lions KT88s, they measured between 51-53 mA. A quad of Tung-Sol EL34s measured between 31-32 mA. I was surprised that my OEM Willsenton KT88 tubes (made by Psvane, I believe) measured 42-44 mA.
I have both MaxiMatcher tube testers for your reference. I find that other mfrs/sellers are more diligent with their testing.
