I'm very satisfied, works good. A tip for customers who want to connect stereo to this mono module, First add to the stereo lines L and R for each 1 resistor of 470 Ohm, for (L) 470 Ohm and for (R) 470 Ohm and connect this 2 resistors on the end together like Y shape. On the place where the resistors are together that's your input and from there you add a resistor of 20K and connect this to the ground line of the input. See picture.
Looks great, have not tried yet. Has 105 C degrees, reg caps
