I'm new to this and trying to make a repair to a pioneer plate amp. The mosfets I need to replace are irf9530 other info printed on them y37k a0
is the other info a batch number? I have found that all irf9530's are not the same. How do I go about buying suitable ones?

What we want to see is the pcb area behind those big black filter capacitors… upper right corner of the pcb. You will probably see IRF530/IRF9530 output mosfets there with lots of smd devices in front. Be careful with knife...that black adhesive material is really pain the *** to remove...don´t brake anything.
You need both, 60-100W incandescent bulb tester will prevent further damage if something else is broken other then output mosfet, you will need multimeter to check output DC offset (less then 50mV DC) and amplifier idling current (50-100mA probably).
