I know I've said it before but I really do think I'm done rolling tubes for a while. I've gone back to the el38 tubes, tall 7n7 input but now I'm using a Japanese 5ar4 instead of the 5u4g I had been using before. Oh, and I'm using this with my active preamp now.
I think this combo would be one of my go-to configurations if I was using a passive preamp. I also love the brown base Sylvania 6sl7wgt with 807, 6ar6 (with adapters), or sylvania 6v6, all with a 5u4g rectifier. The 807 and 6ar6 tend to be too warm and bassy when I use the amp with my 6sn7 based preamp.
Anyway, I do hope others will add their experiences with tube rolling!
