AimTrack Recoil - Failed MOSFETs?
08/18/17 01:00 AM

A few months ago I had a storm roll through and a resulting power flicker had caused my MAME cab to reset.(surge protected).

Yet upon power on I noticed one of my Aimtrack reoil light guns clicking. I looked inside the cab and saw its power brick's LED flickering (36v).
I chalked this up to a typical failure and just opted to replace the power brick. (At the time the other gun had no issues).
When the new brick came I hooked it up, and same flickering LED and light clicking coming from the light gun, so I hooked the new power brick up to the other light gun... Now it began to flicker and the second light gun was making a clicking noise.

At this point I decided to pull them apart and break out the multi-meter. While probing around I happened to notice the MOSFET was extremely HOT so I pulled it from the board to get its part number etc and replace them.

I did after, check all my 36v PSUs with my multi meter and they all checked out (no real load on them of course).

So I'm leaning towards the MOSFETs. The only problem I am having is locating the part.

FQP33N10 with E38 in the top right corner.

I can't seem to find a spec sheet on these, or even a direct replacement part.

Where can I source a replacement or what is an available replacement that I can grab from digikey or otherwise?

I did order a set of FQP33N10 G43 (tested, recoil did not function) and some FQP33N10 J44 (not yet tested).

Or am I even barking up the right tree with replacing this part?

Thank you for my cabinet (under Gallery)
