Has anyone bought the Psvane Acme 300B Vacuum Tube?


These are on my radar but I really know little of them. I had contact once with a fella that re-tubed his VAC Renaissance 70/70 amp with them and said they made a big difference in a good way. It would take about $4K to re-tube my amp with these. I am not in a hurry, just doing research. I can have VAC re-tube it for less than half of this. I think tubes will last a very long time in my amp, especially after I get the MK III upgrade on this amp when I take it to VAC this October. I can also get Gold Lion PX300B tubes for half of this, any one use those? I've had this amp a long time, I plan on keeping it until the grave so I want to do this right their first time even if I have to be patient and wait to afford a re tube. I am retired so disposable income is vastly reduced. I am just thankful i have so many fine audio pieces to enjoy now that I bought many years ago when I could.

I have had the opposite experience to you. I've owned a pair of EML 300 XLS for almost 6 yrs, and they are still going strong with no issues whatsoever. I've had terrible experiences with Sophia Electric Princess 300bs, where I had two different pairs fail. They tried to blame the failures on my amp, which of course isn't true, because they were the only brand that ever failed on my amp. I have nothing but high praise for the EML tubes, they sound amazing and are beyond reliable in my opinion.

100% agreed. I just replaced a pair of the EML XLS 300b after 12 years of very frequent usage in my 300b SET mono blocks. They provided superb sound quality and not a single reliability issue. I fully expect the same from my new replacement pair.

Correction I’ve had the EML XLS tubes over 10 years (purchased in 2012).

Any statement on 300bs without mentioning the driver tubes in my experience is unlikely to be repeatable. In my Wavac EC300b I run Taks and EATs., while both easily beat the TJFull Musics mesh plate irrespective of the driver tube, The Taks work best with Jan Philips 7581as or Svetlana Winged ‘C’s, whereas the EAT loves Tungsol KT66s. In my amp in the end the EAT is the more fleshed out tube for large scale symphonic works whereas the Taks are good for Chamber music and small ensemble jazz given their higher finesse. All of that said, unless you run very high sensitivity horns, 300b is the nicest power tube out there in terms of musicality..I’d hate to think how different speaker loads might further complicate matters….

Many good tube candidates in the hands of talented builders and attention to implementation. I will say that the 300b is a superb tube and has served me splendidly.
