EZ

practice on something else non-blah at first. to solder, touch the iron to the component you want to solder, say, for about 5-10 seconds, then while still holding it there, touch some solder there.

a 25 watt soldering iron is plenty and you want rosin core solder.

now, being a newbie at opening up amps, i must tell you that you can potentially kill yourself opening up your amp. http://www.aikenamps.com/ has good info on their tech info blah. those big battery looking things (large capacitors) are what you don't want to touch.

if you are unsure, take it to a local tech and they can do it (those mods) in about 10 minutes.
 
isnt the amp lethal only if it's on or just powered off?
also where do you get those resistor or caps? electronics store?
 
A couple things for me would be:

- JJ E34Ls, I like 'em, fills out the bottom a bit more.

- Run the presence for your high end, not the treble... If I don't remember the numbers exactly correct, forgive me, but I believe the presence corner frequency is around 3K and the treble corner frequency is around 10K. So, I've ended up running my stuff with the treble between off and 9 o'clock, and I can get my presence up to almost 3 o'clock without it being harsh. What ends up happening is that I start the treble at off, and bring it up until it's not muffled, then use the presence control to set the high end I want... Tends to come out full, and not overly bright.

- I would try the V30s, they don't have the bottom end of the T75s like others have said, but I hate the high end on the T75s, so I find a balance. Right now, I'm using a Mesa Recto 2x12 with V30s and love it.

Good luck.
