Hey man, I see you asking about tubes in your signature...I have heard by many on this board that the SED =C+ (Winged C's) are the way to go for new production Power Tubes, both EL34 & 6L6's...I haven't tried em yet but am planning to order some this week, I will let you know what I think. As for pre-amp, I don't have a whole lot of experience here but I do like the Tung Sol re-issues for new production, I've noticed them to sound better than the stock Mesa tubes - imo.
Good luck.
