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.

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.

Allnic A-6000 monos running 8 x 300B XLS for 12 hours a day for many years with no issues ... and light wear on the tubes (Amplitrex AT-1000 tested). 

 

How do the 1980/2000s or modern Western Electric 300Bs compare to BXLS?

I can also vouch for the longevity of the EML XLS 300b. My first pair in my SET mono blocks lasted me a good 11 to 12 years with very heavy usage and hours. BTW not a single reliability issue during this time. Now on my 2nd pair and anticipate the same outcome. 
 

Not an inexpensive tube but worth its cost due to excellent sound quality and robust built and dependability/lifespan.
