- Sylvania 12SN7GT (the 12V equivalent of 6SN7GT)

That's interesting, for some reason I had previously thought the 12SN7 would not be compatible in the Ember, as it's twice the voltage of the 6SN7. But after checking again it looks like the Ember 2 has an automatic heat selector to roll 6 and 12v tubes. The 12SN7 is supposed to be identical to 6SN7 except for the double current. I take it this didn't sound the best though, seeing that you're selling it.
