I have a problem with my Punch 800 a4 amp. 2 of my caps have burnt out and 1 of the diodes broke in half. I have tried everywhere to find a circuit diagram so I can find out what type of capacitors and what kind of diode I need. I'm guesing at a 6 amp or higher diode, but it's a guess. And I have no idea on which cap I need, it's not labled, it has a color band. I have tried Radio Shack and Fry's, neither have any idea on it. If anyone can help me out with finding a diagram or if anyone knows what I need, please let me know.
