Battery Operation of the PL-P
The PL-P is designed around a
highly sophisticated power supply
system which uses a combination
of rechargeable power cells and an
external AC power supply unit.
The PL-P is not designed to
operate without internal
batteries. The unit is not covered
under warranty if damage occurs
under these circumstances.
The components of the system are
as follows:
• A battery compartment for 8 “D”-
size power cells.
• A DC-to-DC converter module in
front of the battery compartment
which provides an extremely
dynamic and noise-free power
source for powering the heater
filaments and anodes of the
vacuum tubes and other active
electronic components.
This DC-to-DC converter
contains very high operating
voltages and is sealed at the
factory for the protection of
owners, users and untrained
personnel. Unauthorized
tempering with this module is
extremely dangerous and could
result in severe personal injury
or even lethal consequences.
Please refer all service to an
authorized Nagra service
agency.
• An external AC power supply
unit, the PLP-CCC3, intelligently
determines the charging
requirements of the recharge-
