Cary slp-05 tubes rumor or fact?

Thanks Jtran.

I currently run four Hytrons and a pair of Cryo'd gold pin EH. But you now have me considering buying a quad of the Sophias and Psvanes and trying various combos. This could be fun!! How would you characterize the difference between the two?

Regards,

John

Sophia sound like the EH ,but with much better definition and detail.The Psvane is even more detail and very organic.Very smooth from top to bottom.I would recommend having a quad of the Psvane on the 4 left first then a pair of Sophia at position #3 and #6.

I found this interesting explanation of Psvane tubes and its relationship to Shuguage and Black Treasures.

Psvance and Grant Fidelity

It seems that the Psvane 6sn7 is out of production while there new facility is coming on line. And, from the link, Black Treasures may not be available going forward in the US, or if they are they may not be up to the quality of the originals.

The tubes in the Cary newsletter look like they are ST tubes and might be Psvane from the Shuguage plant. Obviously, you can't be sure from the picture.

Dtc,

The tubes in the Cary newsletter are CV181-Z Shuguang Treasure tubes. I asked. BTW, the SLP-05 in the photo was privately owned and the owner had to modify the chassis to fit the tubes.

Kiwi - thanks. So Psvane's 6SN7s made at the Shuguang factory should be pretty much the same, but with smaller bases, if I understand correctly. Guess we will have to wait and see what the new Psvane's are like. From the Grant Fidelity website, it seems that the Black Treasures can vary very widely in performance. Hopefully the new factory will tight that up.
