Donate? Those look so horrible I'd be tempted but honestly I don't have any. You can score them pretty cheap on ebay, aftermarket copies of stock. Hell here's a pair with free shipping, $36
Can't remember if the style like you've got gets rid of the factory circuit boards or uses them...but if you need them then there's ones on ebay with the boards too, brand new. Used boards are a crapshoot..
