LS-36.5DM以主体机LS36.5和独立电源PS36.5构成分体式设计,将原有的供电部分完全抽离主机,并装置另一机身中。供电之元件及线路上加以强化,增设多两枚6EA7电子管,使LS-36.5DM前级获得最理想的供电条件。表现出细致音色、情感丰富、演绎水准达到无懈可击的重播境界。

 

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.
