Power card damaged of Logitech subwoofeer

[anil123verma]

I have Logitech 5.1 multimedia 6150W PMPO subwoofeer (30W+12W*5). Now the problem is with its power card inside it,its ICs are not available in market. I would like to have some suggestions for its alternative (some other SMPS) and from where I can get it.

Power Supplies are power supplies are power supplies. Anything that get you the voltage(s) + wattage necessary and you are good to go, as long as it fits inside I guess unless you don't mind it sitting outside. Yes this will be all DIY and no direct replacement aftermarket, no such easy thing.

Visit a few thrift stores: Goodwill, Salvation Army in the US. Pawn shops perhaps, flea markets, yard sales.....

You may find some speaker sets for sale from which you cannibalize the ICs.

Check ebay - may find an older set or just the subwoofer for sale there.
