Turn the bias pots fully counter-clockwise to see if the current draw decreases.

Clamp the transistors and power up the amp for just long enough to measure the DC voltage across the large 0.1 ohm source resistors. Which ones have more than 0.000v across them?
Do this with no audio. If you have a 2 ohm current limiting resistor, insert it in the B+ line.

My multimeter is not letting me check amperage.
If I turn the power supply of and on a few times it turns the amp on, If I turn it off then back on only a few seconds after it was working it turns right on.
When I wait a few minutes to turn it back on is when I have to toggle it of and on.

It could be that the supply is sensitive the the instantaneous current draw of the amp when it switches on. After you pulse it a few times, the current draw is significantly less because most of the capacitors have charged.
Does it power up with a current limiting resistor in series with the B+ line?
