What kind of specs am I looking for on a tube head that can do the following: Run an 1x15(8ohm) cab by itself Run a 210(4ohms?) and the same 1x15(8ohms) together Any reccomendations for this? Currently, Ive got a SWR 1x15 that i will be running whatever head I end up getting through, then I'm hoping to get an Eden210 XLT or XST to also run with it as well. Ive never had a tube head before, but I've also never fully been satisfied with my sound, and I think some tube warmth is just the thing I need. Also - I am not unwilling to try a half tube head, or tube preamp and power amp deal, like the Eden 550 or something. Also, I'm not completely sure, but the Eden210 is a 4ohm cab right? Thanks a lot!
