Hrm...I guess since this is the first amp I've worked on I wouldn't have the comparison basis. Of course, the layout looks pretty simple inside to me. Maybe I need to find me a little tube amp to mess around with. Or build that little Firefly amp I've read about.
My brother and I are going to attempt this tonight. If I don't write back it's cause I blew myself up! 
Update! Not dead yet! Got the old caps out, and 2 of the three wired in. Ran out of time, going to finish the last one tomorrow.
Woot! Done! Ok, so the hum didn't go away completely, although I believe it's improved. 
BUT the tone is 100x better. It's much tighter and cleaner now whereas before the tone was just nasty and very flatulent. I'm happy with the tone improvement, but are they any ideas on where the remaining hum would be coming from??

It's a .047/1000V Black Cat Paper cap that was wired to the polarity switch.
Here's the question: Is this possibly the source of my hum? And if no, is there any reason to remove it? And if the answer is yes, once removed do you just run a jumper wire to close the polarity switch circuit permanently?

I have to be honest that I simply do not like these things and I remove them from any amp I work on and replace the power cable with a three core one with the green grounded to the chassis. As for the last bit of hum, you are probably never going to get rid of it completely. As long as it's way below the level at which you play, you'll just have to live with it.
Glad the recap worked out well for you.
