I have a bad psu in my TDS-420A , it burned a track on the pcb bur I cannot

the device consists of , or better still does anyone actually have one that
they would part with .
Thanks in advance for any help you can give
I know the TDS420 NON A that i just repaired the power supply on every single capacitor had failed. They mostly looked fine but when you removed them there were puddles of liquid underneath them.
