  Items were tested at 14.3 volts DC on a variable output DC power supply and supplied with a 1000 hz sine wave pulled from the internet to show AC output.  The reason for this is it is tough to show output of a mid and high amp in still pictures.  This is only to show AC output which is what drives a speaker in everyday usage.  Keep in mind these amps are several years old and show a little age. They not brand new physically, or electrically.  I have done my best to take accurate pictures and write a reasonable description.
