Yes, but you need to open the PS to get to it.
Just helped a friend do this last weekend, and it was a pain. Just like OZ said you have to take the supply apart, then all the adjustment pots had glue on the top that we had to chip off to clear the screwdriver slots so we could adjust. Finally we laid the open supply in the cab to adjust it with the game running.
The adjustment would have been much easier if we had some kind of test rig outside of the game to put a load on the supply.

You are right, it was a total pain in the ass to adjust the +5v!
While it is open you should cap it.
Here's a mouser pp7b cap kit from mouser as of today. A couple of he caps from another threading listing mouser cap kits aren't available anymore, so here's an updated list. Hopefully these are correct.

Also, I have pictures of where the pots are to post. What a pain in the ass! I love just about everything about Nintendo cabs, but voltage adjustment blows.![]()
timberterror gave me the cap list I posted above. He said the 27 caps cost him about $13.
Are all of them no longer available?
Can anyone confirm what list is correct?
Thanks.

I'm sure his list is correct. I checked my list against his. I started with the mouser list from another thread and replaced the two cap specs that were no longer available with equivalents from a good manufacturer.
Just to make sure you know the 330uf in you parts list is a snap in. Not sure if it should be or not.
Also, the 3300uf caps should really be bumped to 16 volt and you should use low ESR caps.
