Just had a bargain delivered from an ebay seller.
400w Koac V3 GP 103 two channel High Power Amplifier.
Looks the part, all heatsinks and stuff, £13 delievered, from Hong Kong.
It arrived today and was a lot smaller than I expected.
Curiosity got the better of me so I popped open the case to see whats in there, not a flipping lot and only one Active component with a clearly visible Toshiba part number TA8210AHQ.
Having built a few projects years ago with similar chips I know these are not very powerful and its no surprise to find its rated at 2x20w.
So I’m all poised and ready with as much vitriol as you can get in one line of Ebay feedback to find the pleb has been booted off by Ebay themselves.
There will shortly be a reprisal advert on Ebay for this item feel free to bid!
