look pic IRD 4K5

1. capacitor + / - is wrong in pcb (yellow marked)

2. are the 2 jumper yellow marked right ?
If yes negative (-) Bias is connected with negative (-) rail (- 80 V)

we need only 1 cable for + 12V Bias

3. If I cut Bias jumper from negative rail (- 80 V) then no have short circuit

Hi All

IRS4K5

+95V,-95V 2 Ohms load only.max Current= 47A

then why we need a 3 pair MOSFET??? a single 75A 25 degree 100nC MOSFET will do 4K5 output.

My AUD600 with IRFP4668 gate resistor 39R / 47R with supply +90V -90V will do 4000W 2R load

Regards
MANOJ
