It's cool when you hear those super transparent tubes for the first time. That's what I get from my Amperex 7308 as well. It's warm, musical and so transparent that it indeed feels almost holographic. You instantly know that it's a great tube. Seems like this 6GM8 OG could be cheap substitute for the 7308. Gongratulations for the find!
