GCPS High Current Power Supply
If the GCP-200 preamplifi er does not power up when connected to the GCPS, there are several
possibilities. One possibility is no power going into the GCPS. Check the rear panel of the GCPS to
see if the master power switch power light is lit. If it is not, there are several possibilities:
Test the receptacle feeding the GCPS power to see if there is power coming out of the receptacle.
The easiest way to do this is by using a lamp that you have previously verifi ed works. Regardless of
the receptacle’s type, that of a wall receptacle, a power conditioner, Power Plant or AC source of any
kind, plug the lamp into the receptacle and verify there is AC power.
Verify the master power switch is in the on position. To turn it on, press the top part of the switch in.
The switch itself should be lit.
Another possibility is the line cord. Swap line cords and make sure the unit has power. Sometimes
the line cord feeding the GCPS is not functioning properly. Test both cords if necessary.
If the GCPS and its powered
equipment lose power mysteriously,
chances are pretty good that you have
the GCPS connected to a switched
receptacle on the wall or the back
of a receiver or a power conditioner.
Switched AC receptacles are those
receptacles that are controlled by a
wall mounted power switch and are
typically intended to be used to power
on/off a lamp in the room. Most times
these receptacles are unmarked and
inadvertent switching on or off of
the power switch can cause a lot of
headaches trying to track down the
reason your new equipment does not
power up. Most switched receptacles
are on the top AC receptacle in a two gang box. Always use the lower receptacle on the wall port if
you are unsure.
If you have power to the GCPS and the preamp still does not turn on, make sure the connector
between the preamp and the GCPS is inserted properly. The connector is a Nuetrik style and it must
be inserted and then turned clockwise and locked into place before it will work.
If you have determined the GCPS does not pass power, after performing the above tests, turn to the
service section of this manual for details on receiving service.
Do NOT plug the GCP-200 preamplifi er into the AC wall socket. Once the GCPS is connected, the
