1. Jumper resistor is a resistor (not actually a resistor) with 0 ohm value, usually colored green with 0 markings.
Wire can also be use instead, but must not be very thin and should be as short as possible. Thin and long wire will introduce high inductive reactance and will result to weak received signal.
2. T500 can be taken from 3310 unit. It is located just above HAGAR, refer to your service manual to easily locate it. Also take note to its pin orientation during installation.
Bypassing Z551 with wires is not recommended,this will weaken the receiver sensitivity due to incorrect signal phase relationship.
3. Give special attention when installing VCO, improper positioning will result to no network activity
