What are these mods on my Magnum S-45?

So I picked up a Magnum S-45 and found the following mods inside:

Let's play "why these mods on the Magnum S45:

(1.) We have a jumper soldered between diode 111 on the anode side and resistor 162 near the IC chip.

(2.) We have a cap soldered to resistor 336 that has a green wire coming off of it. Said green wire I'm guessing was snipped from pin 27 and resoldered to a resistor 312 which is near the mic jack.

(3.)Then we have a blue wire in the board right next to diode D248 that is soldered to jumper SJ30.

(4.) Electrolytic cap C203 has its negative lead unsoldered and resoldered to the base of transistor Q183.

(5.) L136, L137, L138 and L141 appear to be spread.

(6.) The yellow wire off of the power/cal knob is soldered to resistor R424.

Perhaps someone can please explain why these mods?
