I've got a really nice Fanatec Speedster wheel for my 1st gen xbox. Today the force feedback from the right side failed (from the left side still works). I also smelled that nasty electrical smell. So I opened it up and found two transistors labeled TIP42C. One has a crack in its plastic jacket, so I assume that is the right side one, that overheated.

Never replaced a transistor before. But have done plenty of soldering and this looks easy actually. Do I have to be careful which transistor I get or will any listed as TIP42C work? I noticed there is a seperate number, 328, on the jacket as well. So do I need to buy one that is 328 as well as TIP42C? Ebay has a TIP42C for like $14 shipped - seems expensive to me. Any place cheaper?

Thanks,
Mark

TIP42C is the correct number. Only thing is that you may infact have other damaged components even though nothing else may physically look damaged? --hard to tell w/out knowing more about the drive circuit?

Depending on the circuit design, there may be a pair of power transistors that could easily be damaged if one fails? (ofcourse it would be easy to check with an ohmeter) Otherwise it can be a guess & it may be just that one failed transistor? Wink

Either way, $14.00 does sounds too high for TIP42C which is considered obsolete but by no means special and can be sustituted. You could probably even get it local.--- on secong thought, with pacakaging/minimums etc, may be just about what it would cost? don't know?

Try some of the following to see if any cheaper?

Thanks for the advice - I appreciate it. I'll go ahead and replace the transistor, hopefully that will alone will fix it.
