Hi,
no problem from 52V to 76V max.
but this special power supply can powered only one amp, independant of current.
not suitable for stereo,two power supply is necessary for this.
this PSU (450g.) emulates very big toroidal with 2x22000uF.

Is it expensive?

Is it expensive?

no, less than a normal switch ...I think.
only 20% plus for version for home use (not commercial PA).
my interest is to let you try (not sell). if you think you can apply on PA-commercial, then send me your private email.
