ok lang ... got a pair for $100. I prefer the Tungsol as VA in my previous 300B. But my current 300B does not use 6SN7 anymore ... a 2A3 in the works won't also use that tube. Maybe later ... to drive an SE pentode which doesn't require much brawn. Our friend in Tisa laughs every time I bring up that tube ... :)

How about the rectifier? Has any one tube rolled the rectifier (5Y3)? What sonic differences are there in any? It would seem that the 6SN7 would have a more pronounced change in sound from tube to tube compared to the rectifier.

TonoMan wrote:I've been asked which tubes are "best" for the Tono violin. Well, I like a lot of them...but mostly NOS. We use the russian tubes as stock on the Tono violin because they are cheap and considered "best-sounding current production 6SN7". Tube-rolling with NOS is advisable on the Tono violin. VD's personal favorites are highlighted in red.

Here's a ranking from TubeWorld. Note where the russian tubes are (bottom of list :-( )- consistent with Patman's observations. Net, tube-roll!!!


"SONIC RANKING
BEST SOUNDING 6SN7 AND EQUIVALENTS (6SN7GT/GTA/GTB/WGT, 5692) ARE THESE:
-----------------------------------------------------------------------
ECC33=CV2821 Mullard (direct 6SN7GT equivalent, superb sound, the best overall, 1950's)
ECC32=CV181 Mullard (can be used in certain applications in place of a 6SN7, superb sound, 1950's)
6SN7W Sylvania "chrome top" 1940's (metal base and black base)
6SN7GT/GTB/WGT Sylvania "chrome top" 1940's-1950's
CV1988=6SN7GT/GTY Brimar England 1950's and early 1970's (Y=brown base)
6SN7WGT Raytheon ribbed plates 1950's

VT-231=6SN7GT Sylvania, Tungsol, Ken Rad, RCA 1940's
5692 RCA Red Base (early 1950's are best)
5692 CBS-Hytron and Sylvania Brown Base (1957-early 1960's)

For rectifiers on the violin, I had very good results on the RCA 5U4G (coke bottle tube). The bass was tighter and more layered. The rectifier provides the foundation signature. Then your 6SN7 will be the icing on that foundation.
