[Boatanchors] NC101X speaker connections

Tue, 16 Apr 2002 18:10:00 -0400

FB on downloading the manual. The simplest way to test the NC-101X is to use a set of high-Z phones plugged into the standard plug on the front pannel.  Use a large resistor to complete the DC path. The resistor will be connected to the fat pins. (I'm not sure of the value.) In the interests of simplicity not attempt to take audio from there now. I'm not sure about what type of xformer that is needed. It's easier and safer to start one of these old speakers. You may have to make a cabinet for now.

The NC-101X is a great rig!

GL & 73,
Jim
