Hey everyone

I just got a hold of an T1000-1bd amp for $20 but the amp is in protect mode so I did the following.

- Took apart and cleaned the amp.
- Verified fuse was not blown.
- Looked for any signs of burnt chips.
- Check the continuity of the mos fets.
- Checked the voltage on all mis fets.

I am a newbie when it comes to working with the multimeter but I do know how to solder. Should I replace all the fets on the boards? I try searching for these parts and find a few on eBay but with different numbers below the part numbers.
Here is a list of these chips part numbers.
P/N on chip:

- 337T
NLBX407 (Qty= 1)

- 317T
NLAV424 (Qty= 2)

- U1620R
CQ422 (Qty=1)

- U1620
CQ348 (Qty=1)

- IRFP3415
BD D5 (Qty=4)

- IRFP3415
BB 19 (Qty=4)

- N430AD
75344G (Qty=4)

- N430AAF
75344G (Qty=2)
