Black probe on the main ground terminal.
Red probe on each of the 3 terminals of each of the PS FETs. The voltages on all FETs should be the same for corresponding terminals. Post the 3 voltages.

No, can you tell me what to do.btw i can use my phone as microlens.
Just few seconds like 10-15 sec.
I meant oscilloscope.
You can take the voltages easily in 10 seconds. Power up, measure on one transistor and power down until they cool, then measure the voltage on the next one.

there is no -12 there. Ground is 0v.
The third terminal of the PS FETs is directly connected to the amplifier's ground terminal. How can you have 0,6v?
The center terminal of the PS FETs is connected to the B+ terminal of the amp. Why don't you have 12v on the center terminal?
Are you sure the meter is in good working order?
