The TSU-1100 is one of our smallest sound decoders, yet is packed with a plethora of high- performance features! This micro 1-amp, universal-style format is ideal for small models with minimal space. It includes an optional capacitor or can be wired to a CurrentKeeper (P.N. 810140) to maintain performance over dirty track and switches.
