That is a mod to lower the gain of the amplifiers. The stock amp gain on some Sega and early late model Sterns (right after they bought Sega) was set high (so presumably the sound could get loud enough in an arcade) and they exhibit buzzing sound from the speakers at idle. This buzzing is very noticeable in the quiet home environment. Reducing the amp gain lowered the buzzing so it isn't as annoying.
