Yes this is the one.

Look at p.4.

Look at where the Power plug connects to 25Z6 rectifier and thereafter. The caps are shown there.

The notation is unimportant - use the one you like. In old sch they simply assigned a number to every part. It is usually not the case today where the reference designator (as it is called) has been made more informative: C is for a cap, R for resistor, Q for transistor, V or D for diodes etc.

If there are three leads and one is grounded (goes to the Chassis) this is likely a dual cap. It has two caps inside, but their Minusses (neg) are connected together and are output as one wire (the one going to the Chassis) and then the other two are positives.

So you usually show it as two separate caps. The two negative (marked with a minus or unmarked, or shown as a curved line) will go to the Chassis symbol and then the two positives (always marked with a Plus or shown as a straight line) will go to their respective destinations (like in this sch - one is before the choke (filter inductance - coil, L-19 or the encircled 16) and the other is after it).
