I have (had) a set of Altec Lansing ACS48 PowerCube Plus speakers (20 watts x2 stereo 20 or 40 watt sub-something like that). Well, I have always enjoyed them, but they were hit by lightning and some stuff in the amp is fried. I don't know what in particular. I now have access to a lot of caps from .47uF-4700uF. I also got some chips. The caps and resistors I can figure out where I can use them, but I know nothing about the chips or any applications for them. They are:
1x TC4013BP
1x TC4011BP
1x Toshiba IC9235P (could be TC9235-the IC is scratched on the top)
2x something- I don't know which number is the model, so all of it from top to bottom is this: ST CHN MC4558CN K00028
1X TDA7294- looks fried to me- has a huge split down the middle around pin #6-8- the board where this pin was is also brown and melted
2x TDA7296 look ok
2x 7812A JRC- then one says MO124J and the pther says G5017A
If anyone know of anything I can sue them for I would be happy to know it. If the schems are too difficult, maybe one of you wants to buy them- they look basically ok, don't know if they work, were desoldered by me from the Altec Lansing board.
I am really wanting to build an amp for a subwoofer though. I don't know how much power I could get out of this, if anyone could help me with any info about what to do with these I would appreciate it.

Those are all inexpensive relatively low quality parts.
Either repair the Altec stuff or throw those chips away.
When going to all the effort for DIY anything less than the best parts is a waste of time. You're going to have 100+ hours in a big DIY project, does it make sense to try and save $2 ?
