Marshall Amplification Marshall MG2FX Guitar Combo Amp Questions & Answers
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
Hi!
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!

Marshall amp troubleshooting
Does anything happen while you turn the knobs on the amp?
I had a similar problem with a yamaha amp. It turned out a couple of knobs went bad. Soldered new pots and it works fine for me now.

Can i connect 2 (2x12) cabs rated @ 4ohms each to my avt50 head?
No, the ATV50 head is rated for 4 ohms total. Using both 4 ohm cabinets at once will fry your amp. Your only option would be to rewire your cabs internally to 16 ohms each by connecting the speakers in parallel, but that would cut your amp's power in half.
