1. The component with two wide pins that looks like an IC
approximately in the middle of the board. It is marked M106 (or it might be
AA106) and 91813 underneath. I think it may be a resistor, but I am not
sure.
2. Just to the right of this is another much thinner two-pin component
which is black on top with a kind of white notch. I have no idea at all what
this is.
3. The three 3-pin black components to the left of the first
component. Two of them are marked "2T L" (or is that "ZT L"?), one
appears
to be marked "2X I" (letter "ih", not letter "el"). I guess
they are
transistors, but they may not be of course, and I don't know their pinout.
My guesses are as follows.
1. That "AA" or "M" looks to me like a Motorola logo. The fact that
this device is polarized leads me to suspect that it's a diode.
2. I suspect that this thing is a fuse.
3. Almost certainly transistors. The center pin is usually the collector.
