The IRF6215's and IRF3415's are the outputs..

Future Electronics has both in stock.. The 6215's are .46 apiece and the 3415's are like .70 a piece

how the heck do u desolder those from the small board

mike49504 · 25th January 2012, 02:50 AM

You need to use a mini butane torch to get them off of the board ..

When you get the new outputs you need to tin them before you solder them back to the board..

THIS link should help. It's for larger transistors but the process is the same.

THIS is a video clip showing the reinstallation.

Let us know when you get them all out, there are a few things you need to check.

Do you have a scope?

You can buy a used one for about $100 plus shipping from eBay.

You can buy the B&K 2120B for about $400 new.
