Bear in mind that these are not official schematics. There is no official schematic, or service manual.

hi !!! VER ----VENDETTA RESEARCH SCP-2A

Colleagues in the shop))) help tell me

Where does the white arrow resistor fit --- to ground?
OR does it go to the foot of the chip then to which?

there are no circuits ----- approximately in an approximate circuit similar to these resistors hang in a pair on the ground


What are the values of these resistors-yellow arrow!?

The white arrow shows the output of the servo (pin 7) connecting to two equal value resistors that return to the input. The yellow arrows are the variable resistors, one controls the input loading resistance, (200ohms) and the other sets the AC balance (20ohms).
