5. Persediaan dan Pemasangan
Follow these steps for proper installation of the power supply module into your audio system. It is recommended to have experience with electronics for this process.
5.1. Identifying Connections
Figure 5.1: Connection Diagram of the Power Supply Module.
This image illustrates the various connection points on the power supply module. Key labels include "Power input 110-220V" for AC input, "Lamp is filament 6.3V" for the filament supply, and "Output 250V or 280V" for the high voltage DC output. Ground (GND) connections are also clearly marked.
- Power Input (110-220V): Connect your AC mains power here. This module supports a wide input range from 95V to 265V.
- Filament Output (6.3V): Connect this to the filament pins of your vacuum tubes.
- Vol Tinggitage Output (250V/280V): Connect this to the anode (plate) supply of your vacuum tubes.
- GND: Common ground connections for all outputs.
- Output 5V: A dedicated 5V output is available for powering a Bluetooth decoder board or similar low-power accessories.
5.2. Vol Tinggitage Pemilihan Output
The module allows selection between 250V and 280V for the high voltage output. This is typically done via a jumper or switch on the board. Refer to the diagram (Figure 5.1) for the exact location of the selection jumper.
- To select 250V output, position the jumper accordingly.
- To select 280V output, position the jumper accordingly.
Penting: Ensure the power supply is completely disconnected from the mains before changing the high voltage output selection.
