Mmats D3000.1 output transistor replacement

[yoppi]

Hello.

I got my hands on an Mmats D3000.1 with the output shorted.
The reference it uses is IRFB4710, but it is now obsolete.
Does anyone know what replacement would be ideal for this amplifier?

thanks

Rochester has them.

In 4080 amps, the IRF3710Z (Z is critical) have worked well.

Would 3710z be a good option? the original 4710 is has a higher Id than 3710z

The original is the better option, in my opinion but I used a LOT of 3710Z FETs in 4080 based amps and they held up well.

OK. I'll try 3710z. thank you.
