Default car amp inverter trafo


i'm trying to build a car amplifier.
i have all of it figured out but i got stuck with two intefearance filters and the trafo.

here are the schematics for the inverter:
and here is the hole patterns that i have:
SP1:Click the image to open in full size.SNT1:Click the image to open in full size.DR1:Click the image to open in full size.

the trafo works @70kHz (or 75kHz, my calculations may not be correct!)
pumps it from 12 to +- 24 volts and it powers 4X75W rms @4 ohms or 2X250W rms @ 4 ohms.
my german isn't great so i think the core is 30X20X10mm that is S=1 sqr_cm
and they say i should use 0.5mm wire (in bundels) and i need 6,1meters of wire total
also it says "1+2e spannung" on the secondary.
