ATTENTION to anyone who is thinking of doing the L4562 mod: The IC is way smaller then you would think. I was expecting 555 timer size (not MDIP obviously) but holy *#&$#. When I got it in the mail I almost crapped my pants thinking of soldering this baby in. After the dust had settled I was able to install it with no problems (braid + silver solder + snips + tweezers + 45w iron). Keep in mind if you aren't 100% confident in your skills, please do not attempt.
