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

I also have the Coincident Frank's 300b and I have tried around a dozen 300b's and my favorite is the KR 300b xls.
They are the test tube shape and they were made in the late 90's. The Frank's are amazing with these tubes ! I have a pair of Black Treasures, they sound good but they don't match the 300bxls frequency extremes, and the bass with the KR's is rock solid.
I am using Coincident Total Victory's IV speakers with a Supratek Cortese preamp and there is definately a synergy with these components.

Charles1dad,

I bought these on Audiogon,about 6 months back,the seller bought them new and never used them.
I'm sure they were new because it took 200 hrs before they started to sound good.At 300 hours I stopped counting the hours and just enjoy them.
Keep your eyes open eventually everything shows up on Audiogon.

Montejay,
I have the paperwork that has the serial numbers and the date of manufacture.
I'm at work now but if you want to know the exact date I can look tonight when I get home.

Montejay,

I checked the date of manufacture, I was off a little.
The date is 5-3-2001 and 2-3-2001 , the test results on each tube are 99% the same.

YMMV but in my system they sound very good .
