ModWright LS 36.5 'DM' (Preamplifier with PS 36.5 Power Supply)
The PS 36.5 Power Supply is an outboard, dual-mono power supply that can be added to an existing LS 36.5 linestage. Combining dual discrete tube voltage rectification and all tube voltage regulation stages along with removing the power supply from the main chassis takes the sound of the 36.5 to another level of excellence. There is an increase in separation, weight, and resolution that has to be experienced to be believed.
Six tubes are used in the PS 36.5: (2) 6H30 triodes for signal gain and buffering, (2) 6EA7/6EM7 triodes for voltage regulation and (2) 5AR4 (and equivalent, including 5U4) for rectification, making this power supply a true dual mono design.
Existing LS 36.5 units can be upgraded or the two box preamplifier can be ordered as a LS 36.5 DM.
We feel this new upgrade offers a substantial breakthrough in value and performance. The PS 36.5 is styled to match the LS 36.5 and rectifier tubes are exposed to allow ease of tube replacement.
