Mohon Menunggu Package : Yes Channels : 2 (2.0) Model Number : TIP41C-1969 Maximum Power Per Channel : 10W Certification : NONE Introduction: The circuit of JLH1969 can be said to be the most famous, it is a circuit that old audiophile is familiar with and novices want to play; however, most of the kits are limited by materials, theranges from low to expensive, and the important components also use non-audio output capacitors. really. . . . Considering that many new students play PCB for the first time, this version will reduce your purchase cost as much as possible while ensuring the quality of JLH1969, so this classic version is developed. Itsis very cheap but the materials are great; The coupling capacitor uses Panasonic BP series, the output coupling capacitor uses ENLA RE3 low internal resistance 4700UF, Panasonic NXL and Nichicon gold capacitors, and ERO small capacitors for sound calibration, Taiwan produces 1% metal film resistors. This version uses a mono structure, MINI PCB can adapt to different types of cases and heat sinks, installation is more free. DIY Kit debugging methods and instructions: 1. After the parts are welded, install them on the heat sink. Note that the output tube must be well insulated. 2. Use two multimeters, one multimeter is set at the VDC voltage position, and the other is set at the A current position. Please refer to the photo below for the connection pen instructions. 3. Adjust the adjustable resistance of R1, so that the value of the A ammeter is DC 0.95A--1A OK. Adjust the adjustable resistance of R2, and use the voltmeter to obtain the value of DC 9V---9.5V OK. PCB Size: 50mm * 50mm Input voltage: DC 12V----24V Output power: 5W+5W 8 ohm, 10W +10W 4ohm It is only suitable for use in small bookshelf speakers or desktop speakers. NOTE 1: The default debugging conditions are
