DC output protection external circuitry
Gday,
picture tells all, have an old amp, needs protection, dont want to modify the insides though, already no room in there, so i need a box that i can run the speakers through that has DC protection circuitry in it. THe circuit must be able to run off mains (best to run off 9v transformer if possible, they are the cheapest) and handle my amplifier which is 80v, or 230w into 8 ohms continuous. Any ideas, please help. Thankyou Daniel |
