Hi all, While we're on the tube coil topic, I am a tube coil virgin (never built one), and I was wondering if someone could point me toward a good reasonable source for large vacuum tubes (811's,833's, ect). I've been thinking about taking the tube coil leap lately and I already have several MOTs and also one beefy 2200v, 1A plate xfmr. Thanks in advance for your responses, David
