12au7 tube?

Try Mazda too.  Fit very nicely between the Tele’s and Mullards, just like you’re looking for.  

@audiojan could be, but  probably more likely Amperex. They probably do sound similar though.

@lowtubes with your expertise in 12au7 tubes, I wonder if you could help clarify something touched on here and something I’m still a little unsure of.  Regarding vintage Amperex, Mazda and Radiotechnique, generally who made what for who? I guess I could ask some of online sellers of vintage tubes but since you’re here and they’re not a clarification could also be helpful to some of the other participants of this thread.

@audition__audio   @lowtubes. Thank you both.  It was my understanding too that all three were an arm of Amperex/Philips. The reason I asked who made what for who is I remember reading (can’t remember where) that Mazda did not manufacturer tubes…they were a rebrander only.  In any case they all do sound different.  I have all three varients of 12au7’s and have enjoyed them all over the years depending on the component they’re placed in, system matching, my mood, etc.

@lowtubes there comes a time where tube life may actually exceed one’s own. Maybe a gruesome thought to some, but may as well face reality, lol. With the number of tubes I’ve collected over the years, I’ve decided to try listening to them rather than just collecting ‘em.  Kinda like money…can’t take it with ya.😵‍💫

It’s nice to know we’re not too crazy despite what our better half will tell us.  

@audiojan also try some RCA 5814’s with your Sylvania’s. They are warmish but seem to go nicely with the Sylvania’s I’ve tried in my preamp.

@inna rumor is PSvane makes many of the Ray’s tubes.
