PM-13:
The MM phono stage of the PM-13 and the PM-11 is the same, two single stage JFET gain stages with a passive RIAA equalization stage between them, and no negative feedback. The PM-13 adds an Amorphous core step-up transformer Moving Coil Pre-Preamp. It is very low noise and is suitable for most low-output MC cartridge.  It’s power supply is the battery (with charger).  The PM-13 comes with a socket type power supply, or upgrade to thr BPS for the best possible performance. 

BPS (The battery power supply with charger):


BPS uses NiMH batteries to provide DC24V output. It has an automatically activated charging function.

 

 

 

 

 

 

 

 

 

 

 


When the battery voltage drops to 20V,it will be charged automatically, still providing DC24V output through the power transformer, until the battery is full.  The BPS will then disconnect the transformer and continue to use the battery.
