In this case, the current pass is so cold when the thermostat is normally closed at 60-70 degrees can be used. The Therm A:, lm3886 normally have thermal protection, but as an additional protection, the thermostat can also be used )optional). If capacitors were to be added it would be nice if, between open. for protection) shielded cable should be selected.Īpart from this, I would recommend that insurance be used in pcbsin. In the same way, LM3886 without coolers metal box, must be connected to the chassis of stars.īounding main supply and AC cables or speaker protection or pictures like that in ( especially hop. Except gndy necessarily need to be metal. Gnd pots on the circuit in a metal box for the line I don’t need to link to. The circuit in o cable with metal card holders or the box where it says ( on the left that thick 1-1.5mm2) the connection should be made. If you used a metal box, that’s my proposal. So necessarily must be connected to the GND line. The main purpose that I used the heatsink for the regulator Tone Control capacitor (15000uF) between the opamp with the shield (shield) on the task. Lm3886 insulate it from the cooler and regulators. The output of the Mean number of lm3886 3, coil 1.2 mm wire leg on top of my fit 10 rounds of resistors 2W resistors, I used this way. Rain for resistors in the 10-15K can be selected according to the choice between. The + and – supply routes, lines and the speaker of the day should be covered with solder. The amp feeds LM3886 Datasheet you exported the file and accordingly these resistors should be selected according to the impedance of the speaker should be calculated. The value for Res tone: (Vamp-20)/30mA power (Vamp-20V)x30mA The value for Res: (Vamp-20V)/70mA power (Vamp-20V)x70mA – you get based on the drawing of the PCB. There are differences between the PCB primarily with photos, some of the material in my hand because of some values in the development stage.
