@carlsbad2 Jerry - Your photos are bitchin'. Looks like a really cool setup, and awesome that you can swap tube types like you describe. That would really have me obsessing constantly.
@atmasphere The RCA shouldered tubes do sound great and are still pretty reasonable. I read lots of raves about 45 globes and the EML varieties but so far I've been pretty content with my RCA tubes. Pretty standard tubes, nothing exotic or crazy except the outstanding sound.
