Section 1: About This Manual This manual is about the VC102 Kit. The VC102 Kit supplies the parts you need to install a volume control into the GT-102 Stereo Power Amplifier. This manual gives the information you need to: Drill the chassis to accept the volume control and ...
Section 2: Installing the Kit Dealing with Metal Shavings Installing the volume control requires that you drill a hole in the front panel of the GT- 102. If you’re installing the volume control into an already built GT-102, then you must be very careful that the metal shavings resulting from drilling the hole don’t short out the electronics already installed in the enclosure.
work. Taking it easy will prevent you from damaging the chassis, or yourself, or turning the chassis into a propeller, or poking big holes in the duct-tape catch basin. Finally, drill the hole out to the finished 5/16” diameter. Remove the duct-tape catch basin. If you “smush” it against the inside of the chassis front wall, you may find it catches most of the metal shavings.
Figure 3-Connect the shielded cables to the volume control. Remember to remove the tab Install the Volume Control Once you’ve attached the shielded cables to the volume control, remove the locating tab (see Figure 3) from the volume control using needle nose pliers. Install the volume control in the front panel as shown in Figure 4-Locating the volume control.
Connecting the shielded cables This process will be done twice, once for the right channel, and once for the left. 1. Solder the drain wire from the volume control shielded cable to the unpopulated INGND hole on the PCB. Cover the drain wire using a bit of the gray jacket from the shielded cable.
Appendix 1: Preparing a shielded cable end This section tells how to prepare the ends of the shielded cable. This process will be repeated four times, at both ends of both cables (although the cables will have different overall lengths). 1.

6. Peel back and remove the foil. Remove the plastic wrap from the red and black wires. The drain (bare wire), red, and black wires are exposed now that gray insulating jacket, foil shield, and plastic over-wrap have been removed. 7.
