Ecc33's can still be had for under $250, I am not an expert on them but I do recall being exposed to a few variations. If they are close in construction we only allow one representative in the tube tests I alluded to earlier. They tend to be easier to find than some of my favorites. Some of the Fivre I heard are decent but not what I collect for home use.Do you like Fivre 6SN7 tubes? I do. It's poor man's ecc33.
Interesting. They used to be more expensive than ECC35, and now seems reversed.Ecc33's can still be had for under $250, I am not an expert on them but I do recall being exposed to a few variations.

It's very easy to identify a fivre 6sn7 from the top:I'm a huge fan. A Fivre black base ladder plate tube is my current fav and has been firmly ensconced in my amp for months. That's the longest I've ever gone without rolling a 6SN7 out.
more then CBS or RCA 5692s? or TS from the 50-60s?I'm a huge fan. A Fivre black base ladder plate tube is my current fav and has been firmly ensconced in my amp for months. That's the longest I've ever gone without rolling a 6SN7 out.
Yes to the 5692 -- At least the CBS/Hytron. Don't know about the TS as I don't have any of their 6SN7 from that era. Of course this is all with my gear and ears. Gear synergy and personal preferences can make a huge diff.
They all sounds similar to my ears. There is a "Air Force" version, sounds slightly better. Let me found the pic.
There are some wonderful GE power tubes out there so it does not surprise me that folks like some of the other tubes.OK, I've got my kevlar vest on so will just come right out with it: I'm running a pair of 1960 GE 6BL7 GTA drivers in Elise and damn if it isn't far better than expected. The treble is actually quite beautiful and extended, mids sounded a bit "wooden" and bass a bit flabby 1st few hours but both are definitely improving as I hit 10 hours or so. This is a 1.5A heater current / high amplification (15mu) triode FWIW, with an energetic sound and I like it best at low to medium volumes. And the kicker: It was $20 for the pair!
Bottom line: These won't be replacing my Ken Rad VT-231 or other favorite 6SN7 tubes but it's good to know there are still highly affordable tubes out there to play with even after I retire and my kids force me into a nursing home I can barely afford. And as for GE bashing, every hobby needs fodder for humor. In the symphony making fun of the viola is a given. Just don't be surprised if on occasion the viola soloist in the Mozart Sinfonia Concertante K. 364 steals the show.
Now back to our regularly scheduled programming.
It is easy to bend to opinions of others but if you like a tube, you like it, regardless of the brand name.
Just as an aside - when I used to play in orchestras growing up (high schools/city youth orchestra) it wasn't uncommon for us to swap instruments for fun during practices/breaks to see how the other instruments played. Viola players always curious about violin and vice versa -- same for a cello and bass players.In the symphony making fun of the viola is a given.

Yeah the ECC33 sound great, but they are not cheap..very nice tubes thoughEcc33's can still be had for under $250, I am not an expert on them but I do recall being exposed to a few variations.
