ITEM NAME:1Pcs 1969 Class a Power Amplifier Board 10-15W HiFi Audio Amplificador MOT/ X2A5 1Pcs 1969 Class a Power Amplifier Board 10-15W HiFi Audio Amplificador MOT/ X2A5 Package: Yes; Maximum Power Per Channel: 15W; Model Number: 1969 Class A Power Amplifier Board; Channels: 1 Product description: PCB: double-sided gold, gold, gold, S wiring, 1.6MM thick Secondary Filter Capacitor: Light Blue Ruby 100UF; Power supply decoupling: boost, feedback capacitor: P-anasonic FC series 220UF Signal amplification tube: 2N2907; Current push tube: 2N1711 Power amplifier tube: disassemble 2N3055( 2N3055 is used, but it work well) Color: silver material: metal Input Capacitor: ERO Angle Aluminum: Silver High Purity Oxidation Angle Aluminum Working voltage: DC 12V-35V (corresponding to 9-26V transformer, power needs to be greater than 100W) Output sound power: 10-15W Size: 100 * 78 * 36MM. Angle aluminum 2 fixed hole distance 53MM The default is 24V, 1.2A, which can be used for current flow. The higher the current is, the more heat is recommended. choose a 3-5 inch full-range speaker, and you can choose a full-range speaker with a 5-8 inch diameter. You can also choose a speaker with a power below 120 watts and below 8 inches. Adjust the current: The universal meter hits the current 10-20A, the VCC line is not connected, the red meter pen is connected to the VCC terminal of the rectifier board, and the VCC terminal of the black test lead connected to the power amplifier board is the measuring current. Adjust the KT2 on the board (W202 at the top of the part) to change the current. 1.2A is recommended. Note: The hole for measuring the midpoint/current red pen is different. When measuring the current and then measuring the midpoint, you must change the red pen hole. Package included: 1pc * 1969 power amplifier board set.Adjust the KT2 on the board (W202 at the top of the part) to change the current. Input Capacitor: ERO. Power amplifier tube: disassemble 2N3055( 2N3055 is used, but it work well). 1pc 1969 power amplifier board set.
