I think I've settled in on doing a JMP 1987 inspired Plexi type build. I'm also set on doing it with an 18 watt power transformer, Hoffman style. Zachmdhunter happens to have some JTM45 chassis with everything punched/drilled except the PT/OT stuff, so that seems like a perfect fit. Maybe I can get them to bundle in the front and rear stainless steel faceplates also. I'm not settled on the output transformer, 6.6k or 8k for the just over 400 VDC B+? I also know nothing about Marshalls. I feel pretty good about duplicating Fenders now, but Marshalls? I don't know. I don't know that I even want to duplicate some things. I hate turrets. I think running the the heaters overhead is a better design. Opinions here are welcome. I'd like to make this look at least a bit like a vintage Marshall.
