Best 300B

Can anyone compare the new Genelex PX300B tube to either Svetlana 300B's, Western Electric 300B's, Sophia 300B mesh plates,newer KR300B tubes or Electro Harmonix 300B's.

From my experience the Svetlanas sound a lot like the Western Electric 300B reissues. New KR300b's are better than the older KR VV32B's, KR VV300B's or KR VV302B's and all the above are better than Electro Harmonix 300B's

My Sophia Mesh Plates sounded very good in my Manley Retros but after several listening sessions I put them back in their boxes because the bias kept changing at the recommended setting. Whenever I get around to it I'm going to compare them to others in one of my self biasing amps.

Thanks in advance,
Ron

Jedinite, no problem. An opportunity to audition a few good burned in 300Bs in a pair of amps you are about to buy is an opportunity to "treasure."

Charles, I envy you. You are only wondering about the Psvane WE replicas. I'm wondering about those, plus the Sophia RPs and your Takatsukis. Not to mention some telefunken 6922s I'm salivating over for my ModWright sony.

I now live just minutes away from the old WE plant. Oh, if only one could go back in time. Just think what one could have done in 1960 with 5K to invest in tubes.

As a boy back in OHIO, I had the pleasure of accompanying my Dad to a local electronics store, and remember well all the cool looking McIntosh and Marantz stuff, with tubes aglow every way one turned. Dad loved to buy tubes. Wish he had held on to a few of his rejects. Well, he did hold on to me, so I guess there is that!

Bill,
Keep in mind your Psvane Treasure 300b is no slouch by any standard. Three current production tubes I've heard in the Frankenstein that I'd consider premium level are,
Takatsuki TA, Sophia Royal Princess and the EML XLS.
The AVVT SL 32B is premium level but isn't current production (and rare to find used). Where does the W.E.Replica 300b fit in? Could be very good given other Replicas I've heard (101D and the 845).

Charles, If I read a review of the WE replicas that suggested they were really in the same league as the originals, that would probably provoke a response. For now, I'm going to hold my cards on 300Bs. BTW, closing is scheduled for the house in TN and the one in Indy is on the market. Once the red clay dust is settled, and I've hiked about 10 lbs of lard off of my gut, I'll revisit the 300B question. I'm enjoying a euphoria of a different flavor right now. My feet are twitching for a good long hike!

Bill,
I know you and your wife are going to enjoy your new home and the beautiful TN. location, getting rid of lard is a good thing LOL. No need to rush concerning the 300b tubes swapping, you have excellent sound as it is.

I have the EML 300bXLS and 300b Sophia Mesh and enjoy them both for different reasons. The mesh do crazy textural audio tricks in my room which makes for just plain fun psychedelic listening, and the EML's sound more powerful more linear and accurate. The EMLs are my go to tubes and if I had to choose one they would be it but glad to have both.
