iam struggling a bit with a amp that power up but gate pads on lo side i think look like this.
high side
when removing mosfets, i have sine wave on low side gate which i believe is quite wrong. what could be the cause of the sine wave or noise directly on the gate pad?
below shows waveform on gatepad with 100hz on rca

is it normal for -rail to drop significant faster than + rail? or has it something to do with a short?
