@Scott Kramer I am indeed! But I went rogue: Okay, okay, so I have a few 6SN7 to use in the Freya, and I already had some socket savers, so I just needed a pair of 6SN7 to 6922 adapters. DON'T DO THIS. ...in practice a 6CG7 is electrically identical to a 6SN7, so the overall sound is pretty much the same. The 6SN7 do seem to have a slight edge, like maybe 5%. Haven't experimented much with different 6SN7 as I've been digging the speaker setup of late.
