Dunlop DC Brick mod

[philbinator1]

Hi all,

I'm wanting to mod my dc brick so 2 of the 18 volt outputs are 9V.  Is this possible?  I couldn't find the schematic, only the manual

I would suggest using two 9V regulators, one for each output. Something like this:



Instead of a 7805, use a 7809.

what is the diff between the 7805 and 7809?  which pins would i go to with input/output/ground?

7805 is a 5 volt regulator.
