I built the SE5A two years ago - it was my first proper valve map build and it went very well. Th eamp sounds good, but I feel that the PP18 sound much better. When driven hard the PP18 has a much fatter sound.much more satisfying. What I intend to do soon is record a few short clips comparing the two amps. In the meantime here is a pic of the two Ampmaker amps together on top of my "Marshall" 4 x 12.....
Bye for now
