Planet audio ac4000.1D

[Mjimenez]

Hi friends I ask for help to repair this amplifier of the Planet Audio brand model ac4000.1d initially all the output mosfets were in short, I removed them and checked the vertical plate and found 2 damaged transistors mps056 (Q6k and Q7k) and 1 resistor of 100ohms now my doubt is that signals or voltages I must have in the connections of the output mosfets to be able to install them and I mention that the output inductor likewise checks it and I did not find anyting, the voltages faith + -15v if I have them the VPP is also present Greetings to the whole community
