I was recently given a Spectrum 300 plasma that's not operational. Looks like two of the main power transistors have popped, unfortunetly bad enough that I can't read any kind of part number on them to source replacements.
Is there any way to get these numbers, short of buying a replacement board? I've attached pictures of the affected units, and in the wide shot, it would be the 2nd and 4th heat sink from the left.
I can handle the replacement no problem, I'm quite familiar with working with electronic components, and have the full service area here at the house for electronic work - temp controlled solder stations, hot air station, static controlled work area, etc. Just need to know what transistors are in there, lol.
Also, any idea what would have caused this?

Unit had a massive power surge, and to blow these power mosfet, rest ssured thats not the only issue. Best toss the project.
