Psu15 Power Supply - Signal Audio Workshop CH2-M Owner's Manual

Psu 15 power supply:
The Psu 15 unit is an all
discrete CLASS A topology,
made with massive
filterazation, designed
especially for the lowest noise
floor needed in microphone
amplifying.
For a fact: Pre amps noise
floor is constructed from the
amp's self noise + its Psu
noise floor.
Therefore noise floor issue is very important when dealing
with a 60db gain machine. This is why we engineered an
uncompromised Psu that is suitable to deliver an ultra low
noise floor.
Features :
+300 vdc B+ voltage highly regulated for tube plates.
+50.4 vdc voltage for tube filaments (regulated).
+48 vdc phantom power (regulated).
+/-24 vdc for vcc to solid state electronics (regulated).
The Psu 15 can be internally modified for 220 or 115
vac operation (must be preformed by qualified
technician!).
Always make sure that the unit operates on the
correct mains voltage (230/115 VAC) before
applying mains voltage!
