Look at this attachment!
Do like this
1. If you find 1n0 and 150p, just ignore it to simplify your work.
2. If you find 2k2 and 50 R, it means you got to make a jumper from the point to the another. For example, from C1 to A2, we have to make a series of two ressistor( 2k2 and 50 ohm). Find this resistor from another phone.

This is terrible....isn't it? Because R2100 is quite small. So....Why dont you JUST CHANGE IT....

To MUTUAL
You can see the resistor that attach by Efrom. GOOD JOB, Mr Efron!! But I know that you miss the track, dont you?? So what you got to do is look again in your N70 Schematic, and see the connection from the missing point. Do jumper from that component.
Good luck...
