Panasonics VHS Issues

[tvcollector]

Ok, Now I've got alot of my Panasonic VHS VCRS up and running with new Electrolytics.. I've got a few decks that burns out the 1.6 amp fuse, even after replacing all the electrolytics.. I've did some searches and read something about that it's got something to do with zeners and regulators also.. Anyone know? I'm guessing previous owners used them to the point the electrolytics got really bad, causing other components to fail..
