Upgraded Dynaco FM-5 Tuner


I just picked up this Dynaco FM-5 Tuner from a second hand store. It works fine but when I researched it for more info I noticed mine looked a little funky from behind. Someone added some caps and the whole back end looks very modified.
Anybody have a clue as to what might of happened?
Thanks
Here is a link to some pics:

Wow just look at those cans!

Someone significantly beefed up the power supply by enhancing the filtering; should be a good thing!
Can you show us a picture of the connections inside the FM-5?
