In aFender amp there are a few things that will make a fuse pop. A leaky filter cap will certainly cause a problem, as will a leaky cap across the cathode bias resistor. But the very nastiest ones are tose capacitors coupling to the output tube grids, because a leak there will also cause the tube life to be shorter by a large amount and possibly burn the output transformer, an item expensive to replace, if it can be found at any price. That is why I recommended replacing them with 600 volt units, or even 1000 volt caps. And the low leakage ones were the best choice.
Being a huge Fender fan, I gotta ask, why in the world was the fuse blowing? The only one I ever took out was when my drummer knocked a Coke bottle off my amp and something akin to a Mentos fountain showered my 6L6s. The Coke shorted the plate to the filament, wiping out a 6L6, opening the hum balance control and burning the fuse. Fortunately there was a spare amp because it was the opening tune.
I had a plasma TV that would frequently open its ill-sized, mini fuse. I was sure it was simply getting too hot in the fuse holder, so I replaced the fuse with a breaker that was carefully selected to have the same current and trip time specs.
While I do not recommend smashing power bricks on the floor, I certainly agree with opening them to see what has failed. Poor solder connections are one of the easy to repair problems, and I am happy that the repair has continued to work for you. Of course, being open with no case probably makes the power supply run a lot cooler, which also helps.
