What in the heck were they thinking when they chose that IC ?>>>?
Great for a cell phone but a guitar amplifier?
Come on !
Good job midibob!!

Yep, my thoughts exactly. I did get some sample chips from Texas and replaced a couple but it was a hell of a job even with all my SMD stuff and a microscope. That's when I thought there must be an easier way. The icing on the cake was not having to remove the old chip. :dbtu:

Here's a copy of the installation instructions but I must stress I don't make them anymore and don't have any!

Fantastic job, looks really professional!  No worries you don't make them anymore, still a very interesting share!

To replace the ic properly the balls on the pcb have to be reflowed.
They make sheets of teflon with the correct spacing holes in them & you simply lay the sheet over the flattened balls apply flux and reflow the them.
