Who does make Trainwreck Express or Liverpool-inspired amps? I know (of course) there is the Komet, Fuchs's Train 45, and RockyTop is talking about making one. Any others? The TW-type amp seems to be a "wide open" amp; I would imagine component selection would be crucial. Has anyone ever taken note of what types of caps/resistors and transformers KF used for these amps?
