I'm going to base these questions on the output potential of KT88's. I'm comparing the Reeves Custom 400 to the new Mesa Strategy (300W). Both amps run KT88's, the Reeve's has 6 and the Mesa has 8. But the Reeves output is 100W higher. I am assuming this is where the output transformer makes the difference. What are the advantages/disadvantages of the different confiigurations? It is a technical preference or does it change the tonal characteristics?
