I recently purchased Sylvania 6SN7 GTAs (chrome domes) and Hytron VT 231 6SN7 GTs. Are both okay to use in my Schiit Freya +?
Yes! See manual below:

6sn7 tubes and Schiit Freya +
Hi all-
I’m a new Freya plus owner and just getting ready to move beyond the Stock J&J tubes. I was reading a thread about 6sn7 tubes and saw this—
The 6SN7GTA and GTB versions were introduced in 1950 and 1954 respectively. They have ‘upgraded’ ratings, which are as follows.
GTA: maximum anode dissipation upgraded to 5W (the GT is rated for 2.5W)
GTB: identical to the GTA, but with a controlled heater warm up time for use in equipment with 600mA heater strings
This is significant because it means that a circuit designed around the 6SN7GTA/GTB cannot have 6SN7GTs substituted into it. Substituting a GT in place of a GTA/GTB in your equipment will precipitate its rapid destruction and possibly damage your equipment.

That is quite the snobby statement. @mcanaday do what you want and buy what you want. Like these folks are less deserving than people who paid to much for their Cary.
