Hi I'm YarJr. and I have a Sega Genesis question so what better place to ask than an atari forum? lol (was not going to be my first post here but since I have a legitmiate issue might as well ask. I should be talking about my lovely Atari jr. though)
See Ive been ressurecting my old consoles and I lost my power supply and a/v cables for my genesis so I picked some up but the damn power supply is for a genesis 1 and I have a 2 and 3.
My question is could I use a Sony 7.5 v supply with an input of 120v ~ 0.37 A and an output of 7.5v -2.0a for a Genesis 2 or 3?

according to the first site I googled the gen 3 needs 10 volts 300 ma, considering the first thing it will hit is a 7805 it might work in regards to voltage (depending on what reverse polarity protection is installed in the machine) and has plenty of current.

current is safe as the system will only take what it needs from the power supply's potential, but you are really close to the low end on the voltage.
