Aball is right. 99dB sensitivity is quite high, especially when your sub is powered, so you don't need to look at 25-watters. 3-10 watts will simply blow you away ... for all of the right reasons. Just do some crit research. I wouldn't spend mega-dollars at first, and I don't think I'd even consider 300Bs at this point, at least not before you know that tubes are where you intend to stay.
Tube amp, size and power info........
I am geting a new pair of speakers wich are 99db efficient with a plate amp for the woofer, I have a tube pre but now I can entertain tube power but I want a reasonable price to try and also it needs to fit in a standard rack space (6.5 inches) I would say that anything above 25 watts will do, my pre-amp is a Sonic Frontiers and my usual volume is low to moderate, never obnoxiuosly loud, what are some options that wont break the bank, I know it isnt much but I am talking around $500 new or used.
