Mod your Beresford 7520

Don't bother unsoldering the opamp, the easiest way is to use a stanley knife. Press against each leg one at a time with the tip of the blade and the knife will cut straight through it, you dont need to use alot of pressure and it will beat the frustration of trying to remove it using the iron alone.

When it comes to soldering the new opamp in place give the following video a look:

If you have the chance practice on an old unwanted circuit board to get comfortable.

If using solder feels too tricky, buy some solder paster and make light work of the job.
