I recently purchased a JTM 45 100 board and chassis, pre assembled from Ceriatone. I'm on a shoe-string budget and wanted to get the rest of the parts locally, here in the USA. I tried Weber and Marsh amps but they told me to get a list of individual components together since they would not merely subtract the parts I already have and provide a partial kit. That's fine except I haven't a clue what I need, part by part. I had assumed I could just ask for everything needed for the output stage of the amp, also not knowing what parts besides the tranny's would be JTM exclusive. I figure most of the stuff is JMP guts before the tranny's but hey, it's my first build. Also if anyone knows what company besides Weber or Marsh could fill my order without taking it personally, that would be great.
