As of now, all MGL100 & MGL50 2-channel amps are 100% NOS mustard cap circuits and come with NOS RFT Siemens EL34 power tubes & NOS Chinese square foil getter 12AX7's. I constantly search the world for mustard caps to buy. Many new caps sound good but nothing has a more authentic Marshall voice than real mustards!! 100's of them is a beautiful sight
