here is the schematic.  By looking at the schematic do you see anything I should check? And how should I test it?  http://www.bnv-gz.de/~ooehmann/dexer.php?d=fender

Thanks for all the help on my last post.  I fixed the problem with the hum.  And I was wrong and felt like a dumbass.  I did put the caps in backwards.  Ive been trying to teach myself electronics for about a 1 1/2 years and even though I thought I understoud electrolytic caps, I was thinking the - stripe was the + indicator.  Lesson learned, I'll never make that mistake again.   Luckily, I didnt wreck the caps or anything else, I hope.  I put them in the "CORRECT"  way and the hum is gone.  It sounds clean and crisp.  However, The drive channel switch doesnt change from drive to normal. It is stuck on drive. I took the switch out, checked it and it "seems" fine.  Is there anything else that it could be?  I'm thinking that it has to be the switch.  When I push it, nothing happens.  Any advice.

I just took it back apart and desolderd the caps.  I did put them in right.  I tested them again with my Dmm.  What other tests can I do on these caps to check their condition?
I had the schemadic once but cant find it and dont remember where I downloaded it from.  I've been to schematic heaven and the fender field guide but neither has this schematic.  Any sites I should try?  The board felt dry, I dont know if the paste I used could have squished together when I pushed the capacitors down on them to short out the caps.  Any paste would have to be a good electrical conductor, wouldnt it?  Dont know what I did wrong maybe I hooked one of the power lines on wrong.  I really dont think so but Im going to find the schematic and double check everything before I try to plug it in again. 

Ive been working on a fender deluxe 112 plus -which has a loud humm as soon you turn it on.  with or without guitar plugged in or volume turned up.  The two large capacitors 50v- 4700 uf seemed to move alittle bit.  While the amp was on I moved the two capacitors which were connected together with a hot glue gun, and the hum stopped. I took both the capacitors out, checked them with a multimeter.  they seemed to be charging with the multimeter set on 20k ohms.  So I cleaned them up,along with the holes they went through, put alittle soldering paste on them and resolderd them back onto the board.  When I turned the power on, the hum was gone but I could hear another noise and then 30 seconds later the fuse blew. I dont think I shorted anything out with solder paste, if you even can,  but the noise I was hearing could have been the sizzle of soldering paste.  After the fuse blew, I shut off the amp, unplugged it and touched the capacitors and the were very hot.  Almost to hot to touch.  What damage could I have done?  Did I do the right thing? Any other thing I should be checking?  ect.
