Amp turns on but puts out no sound except for faint noise which dies out after a few seconds.

It sounds like a defective/incorrect AC-to-DC adapter may have caused your problem. These adapter come with different output voltages, AC or DC output and different amperage ratings. AC-to-DC adapters list the polarity of the DC voltage as it relates to the DC power plug and you must match both the devices voltage and power requirements. As for the amp...not working on batteries either, I would suspect output transistors or IC.

Marshall Amplification Marshall MG2FX Guitar Combo Amp power turns on but no sound

At this point, I would just take it to a tech rather than poke around in it. It sounds like the power section is the problem as you have guessed, but without the technical knowledge you'd be shooting in the dark. That particular amp is right on the line of being expensive enough that would be worth repairing, but you might do just as wel to check Ebay for another used one.
Good Luck!

Alesis Quadraverb Q2. When I turn on Alesis Q2 the programs 1-100 preset are working but when I turn on programs 200-300 user It does not work. There is only "bad program" characters on display.

The Problem is a dead battery which is soldered to the circuit board inside the unit. It's a Panasonic BR-2325-1HC, but really you can replace it with any similar 3V battery.
Here's how I fixed mine.

Alesis Multimix8 started smoking and now won't turn on. If it is a fuse or something how do i replace it?

A blown fuse will not produce smoke. A component failed and probably fried a resistor, which would smoke. That in turn would blow the fuse.Just replacing the fuse will not cure the problem. Your unit needs repair.

These subs arent loud

The subs are rated at 133 Db peak... that IS loud. Note that the crossover is 90Hz so ONLY the very low frequencies will pass through these... possibly your input frequencies are above this? Everything above F2 will be attenuated and will have to go through other speakers. From this chart:

You will notice that ONLY the LOW END portion of a bass guitar and a few other instruments will oass through this unit. It is up to your mains to handle things above 90 Hz. These subs are truly subs. Make sure you use balanced lines to drive these. (XLR)
