I use the Psvane WE300B on good quality SET amps, and I very very very highly recommend them. Nothing to criticize at all; the mids and highs are just the best i have ever heard. The only tubes that may beat them, and I also use them on another system so I know what I am talking about, are the famous and highly expensive Takatsuki TA300B, that output more bass but less glorious mids and highs. It will depend in fact on the nature of your speakers and/or your preferences. For your reference and comparison, the amps using the Psvane WE300B are the Coincident Frankenstein 300B MkII. The tubes you are using are known for being unreliable.
Psvane 300-B Tubes ? ? ?
Does anyone out there have any experience with Psvane 300-B MKII or their WE300-B Replica tubes ?
I found the best sound from initially the Sophia Princess mesh-plate 300-B's, then their Royal Princess 300-B's however I'm definitely NOT happy with their reliability, especially the Royal Princess !
I had a mesh-plate from new have a glowing spot on the mesh-plate, and they told me it was from sitting on the shelf for over a year ! REALLY ! ? ! ? And I had two Royal Princess tubes go out with less than 600-hours on them, unfortunately well-past 1-yr. warranty. Left a bad taste... I'm NOT going back...
I've tried EH gold-grid 300-B's, Gold-Lion's, JJ's... All sound somewhat different but the Sophias sounded the best, however in my experience, reliability is questionable... Thanks... John
