HUF75343p3 replacement

[DerSamoaner]

Does anyone have practical experience with a replacement for the mosfet huf75343p3?

Digikey recommend the STP80NF55-08AG.

Gate resistors are 18 Ohm.

These mosfets are in a Steg Masterstroke 3000 power supply.

I've used IRF3205 and 33-47ohm gate resistor whit no problem.
I've rebuilded 15+ masterstroke msk3000 in this way and never had problem.

What about the IRF3205? I don't know this amp but it works as a good sub in most amps.

Thanks! I will order the IRF3205 and Gate resistors.

IRF3205 with 33 ohm gate resistor works fine. Also changed the driver BD139/140.

Thanks a lot.

I'm searching this diode. The left one is shorted. Driver board output section.

I see only one blue stripe on the cathode.

Any idea?

Maybe put all parts back and measure the voltage on the good one?

It's a 6.8V zener diode.
