Can anyone help me identify a transformer I bought around 2007 from Metroamp? I'm pretty sure it's a power transformer (forgive me because I haven't done any amp building for several years), but just not sure which one it is. I've only ever built three Marshall clones in the 100W, 50W and JTM45 varieties so it has to be for one of those. I sold the 100W years ago and experimented back and forth with the JTM45 and JMP50 models. Hopefully this narrows it down some. Any help is greatly appreciated. Thanks!
