WantzChas http://www.randallamplifiers.com/products/amplifiers/mts/modules.asp How exactly does it work? Is it just the pre amp that you are changing?
AlanRatcliffe Yup - just the preamp. As a design, this modular preamp design can only take you so far, as much of the tonality of many different amps comes as much from the power stage as from the preamp.
