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

If the US representative of Takatsuki had offered a demo 300b pair to "try," I would have bought my tubes from the US distributor rather than sourcing them from Japan.

I suspect that each of us has tubes that we do not use. For example, I have a new pair of EAT300b that I would be willing to contribute to a co-op venture. I wonder if manufacturers/distributors would be interested as well.

Charles, I would have pegged you for a Brothers K. kind of guy.

Hey everyone

I just want add this extensive tube roll test of a good amount 300B tubes done by the late Ian Grant of Grant Fidelity for everyone to review.

He covers a lot of 300B tubes so I hope this helps everyone.

Also I want to say Thanks again to Brownsfan and Charles for their input on the 300B tubes. I'm going to enjoy the stock Electro Harmonix 300B tubes in my Bottlehead BeePre preamp for now and then I'll start the tube rolling madness. 300B tubes can be really pricey and I want to avoid the buy try and re-sell at a loss cycle that I've gone through in the past. I do wish there was a 300B lending library but what can you do.
