The Hiraga Prepre

This pre preamplifier is designed like the legendary pre pre amp by Jean Hirara (Le Prepre).
It is the missing link between the 2 phono systems MC and MM.
It is the gerneral start up version with a minimum of capacitors. You will need to add serveral packs of capacitors
in the power supply unit. Here you can find some more information about the powering:

This Prepre is great and economic alternative to a classical phono preamp with expensive transformers.


We offer you for the Hiraga Prere a kit and materials.
