If building a 300B SE, what would be more prefer for coupling between driver and output stage? Interstage transformer or capacitor coupled?
I've seen someone built an amp with 6922 DC coupled to 5687 and transformer coupled to 300B, but also have seen one with same tube complement but capacitor coupled. Pros and Cons between 2 different approach?
I heard transformer coupled is more efficient.
