Question on tube load resistant & output trans (need adv

Someone had already answered your question.

I am using a DIY 300B driving a pair of JM Lab 926 modified with premium parts of course. the amp can drive the speaker with flying colors. I think whether a SE amp has enough power to drive a pair of speaker is really depends on the design and parts of the amp. However, my case is a abnormal one, so do not count on it.
