Good evening guys, I’m have two issues already with this amp, the gate resistors are burnt beyond recognition (I assumed 100ohms based on the Sony schematic).
Secondly it uses 70N06, can I use the 3205 with 47ohms resistor in this circuit or just replace parts with the original part name?

Typically, the transformer driven amps are not as critical when it comes to gate resistors. The 47 ohm gate resistors with the 3205s should work if that's what you want to use.
I’m currently about to replace the gate resistors and mosfets (47ohms and IRF3205) on this amp but powering it up without gate resistors nor power mosfets, is it a stepped pulse for the gate drive I should be getting?
This is likely perfectly fine. It won't look like a normal drive signal since it's a transformer drive supply.
