HI,
Can someoneplease identify the tranisitors for the mag board on lah and the shaker motor board, thanks

I think they are IRL540

IRL540s are the upgrades for the magnet board

If one is bad, replace all three and the IC. Watch that board too, the traces and pads are the worst I've ever seen. Almost any heat was bringing up some pads.

They MUST be "low level logic" types meaning they can be driven from 5V TTL logic (as they are on this board).

The part number "IRL540" says it all - the "L" signifies Low Level drive.

Normal MOSFETs CANNOT be used - they will not work.
