Oops, poor file management. Note that the 4N26 opto coupler is already in the spice library.

What are you trying to do with the amp when it's burning the resistor up? Do you have fuses installed? If so F2 is blown.

You have a blown fuse or bad solder joint on the fuse holder then. R53 and R54 shouldn't be doing anything once the fuses are installed.

Hi John, Sorry to be a pain but it looks like to simulate your amp I still need another include file -> "DIYAamp.txt"


If you could post this when you have time that would be great.
