I am gonna get a backup amp one of these days and would prefer a 50 head, but these are getting really hard to find. Sure wish I would have done it when they were around more but no.... I sure don't need 100 watts but I can pull tubes to get 50. How about opinions on the 100 watt amp with the 2 tubes pulled. Does it change the way the amp reacts in any way or is it just a loudness issue. The 50 is such a great amp for Marshall based modules with el34's. So lets hear it, is the 100 better than the 50? Any difference?
