The Modwright LS 36.5 DM takes the performance of the LS 36.5 to the next level by adding the PS 36.5 dual-mono, all-tube external power supply. This PS 36.5 features a complete dual-mono topology, including dual tube rectifiers and tube voltage regulation circuitry.

Other features include true balanced inputs and outputs, refinements in power supply design, voltage regulation, and driver circuit design all serve to raise the bar. Refinements in grounding, transformer coupling and shielding also yield a 2 x lower noise floor than its predecessor!
