Taramps 5K amp

[hanzooo]

Hello,
The amplifier burned out, do you have the value of the grid resistor and the reference for IC4 ?
Thanks

Someone will have more definitive answers but the driver IC is likely a UCC27524 or something similar.

Grid resistor? Gate resistor?

 

[hanzooo]

Sorry, gate resistor

 

[Perry Babin]

The gate resistors will all be the same. Did any survive?

 

[hanzooo]

No, all of them burned

 

[Perry Babin]

What are the PS FETs?

 

[ultra]

What is the version you have there ? There are a few using different parts

Sorry, gate resistor

Looks like a 10Ohm gate resistor and 1k for pull down

Looking at the picture you have provided that resistor looks like a 10r. Without knowing the version that you have it is hard to say. @ultra mentioned this. If you use IRF1404 in the power supply like the MD 8000, you can use 10r resistors. As per the schematic that I have for the MD8k with the IRF1404 they use 10r resistors.

Hello,
Sorry for my late respone.
It's a V2 version, PS FETs are CSD18502KCS, i can replace them with IRF1404 ?
And yes it's a 10R gate resistor

 

[laluns]

Yes you can use 1404

Thank you
