I came across an old thread: http://forum.allaboutcircuits.com/showthread.php?t=17729 (I hope a link is ok) that listed some details about what I want to do to my dock, but it was too old to accept replies and I just wanted to clarify what I have read so I don't mess anything expensive up.
So, I need to put a 7805 regulator between the 9v wire coming off the board and connect it to pins 23 and 15 on the ipod dock. I also need to use a heatsink.
Then I need to tie pins 25 and 27 together with a 10k ohm resistor.
This is all assuming my dock has similar innards to the above docks as I haven't opened it yet.
Some questions:
Does the above sound correct?
Is the heatsink TO-220 heatsink Radioshack# 276-1363 or the TO-220/TO-202 Aluminum heatsink Radioshack# 276-1368?
My dock is also a Klipsch like the last post in the above thread, but a roomgroove instead of an igroove and it worries me a little that the current did what it did. Does anyone know why this happened? I don't really understand the "5V zener and 100uF cap across the 5V rail and ground" part of the post, but do you think I will need to add this?
Sorry for the long post, but thanks in advance for the help!
