Hello, this hifonics zeus amplifier has exploded the mosfet irz, I would like to know if the resistances that Q8 and Q7 have are normal. Is this amplifier stable at 2ohm in mono?
If you're asking if the point-point resistors are normal, they are in some amps. You can find photos online showing them.
Not 2 ohm mono stable.
It appears that the primary capacitors have saturated the board with electrolyte. If this is conductive or becomes conductive, it may cause the amp to fail, catastrophically. If the conductive area begins to heat up, it could cause the board to begin to burn and it may not stop until supply voltage is removed. Removing remote will not stop it.

okey r37 and r36 are fine 56 ohm, all the gate 220ohn resistors of the mosfets were replaced by 47ohm without mosfet set I have a perfect cudrsda wave and a voltage of 4v in all the gates if I measure from gnd to collector of the tip 36c or 35c tebgo output +16 and -17v apparently SgsD100 and sgsd200 limit that voltage since if I measure on leg 1 and 3 of the sgsd100 I have -56 and in sgsd200 I have + 56v
Are you saying that there is absolutely no drive to the FETs with the FETs in the circuit?
Try a different translator.

If you see a wave as a deformed non-square sine wave, and with a multimeter it marks 0.2v dc but without the Transistors I can already see a good square wave and with the multimeter I have 4.1v dc in all the mosfet gates
Post an photo of the waveform that reads 0.2v on the meter. It's likely OK but seeing it will make it easier to tell if it is or not.
He switched the gate resistors from 220 ohm to 47 ohm would this have anything to do with the bad drive signal since Zed used the 220 gate resistors since there is a lot of dead time in these amps?
You must use DC coupling and must include the scope settings for the vertical amplifier and the timebase.
The trace must be aligned to the center reference.
use 10us and 5v/div.
