Default Directed D2400

This amp is using IRFZ48's with 22 ohm gate resistors in it. The power supply is blown in the amp i have here. Wondering if i can swap the 48's to 3205's or 44's? And if i can will the 22 ohm resistors work or will i need to switch them also??

The 3205s would be a better choice than the 44s. The 22 ohm resistors should be OK.

Perry,
Do you know what rectifiers belong in this amp? They were missing when it came in for repair

And second one.Both amps use FMU36S and FMU36R.Practically not possible to find in US.In some D2400 they also install Mospec F30D60A and F30D60C.You can find replacement for common cathode rectifier ,for example RURG3060CC

If the rail caps are rated for less than 200v, they FMU34 would work. Have you found a cheap source for them? Kenwood Parts has them but they want $10 a piece for them.

The center leg of the 34R produces the negative rail voltage. It should connect to the negative terminal of the negative rail capacitor. The positive terminal of the negative rail cap will be connected to the secondary center-tap/ground.
