Title: Sophia Electric Tubes
Post by: jimbones on February 12, 2019, 09:51:14 AM
Anyone ever use Sophia Tubes? They make 6SN7's called "electric blue glass" look interesting

  Jim lots of chatter about these tubes. The Black Treasures appear to have better tone than Sophia. NOS Tungsol Round, oval plates are still the Cat's meow. Brent Jesse Tubes or Andy at vintage tube Service. I got Tungsols matched at $100ea for the Wytech preamp.

I currently use NOS (forget which brand) but I got super low noise from Andy at VTS. Just wondering how the Sophias are. I did have the Psavane Black at one time but the NOS were clearly better (no pun intended)

  Only one way to find out try them.

I have run a lot of Sophia tubes including different 300B, 6SN7, 12AU7 and a couple others. I do like the 6SN7 and it was standard in our Purity Statement preamp.  I love their 300B tubes but now looking at different options for the new Purity 300B buffer. Did not find the 9 pin signal tubes to be anything special.
Do this day, I still run their 274B tubes including the rigid.
