I also tried the same pedal setup and voodoo lab power +2 with my laney 50 watt combo tube amp and it also likewise crashed. on both the result was the same - all the tubes were running and the lights were all on tho i couldn't get any sound whatsoever from either amp and right before the amps totally crashed, there was a crackling sound coming out of the speakers and then a very loud POP and then nothing but lights tho no sound at all. the marshall blew a fuse which i replaced and tho the amp is now running it has this horrible pop sound when i put it on standby. the laney i managed to pull the plug quickly enough before it did any real damage after seeing that it was reacting the same way as the marshall had previously so it played the rest of the night fine AFTER i took the voodoo lab power +2 out of the loop and just ran my pedals on batteries. the only common denominator to my problem is the voodoo lab power +2. neither of my amps EVER had a problem before i hooked up the voodoo lab power +2.
How do you have the DIP switches set? That controls the voltages.

Very nice amp!
First off, is the amp getting sufficient power? An unreliable AC current from your wall can affect the performance.
Have you tried the amp with a different speaker? Checked for a loose connection from the amp to the speaker? Is it the correct ohms rating?
Second, are you experienced in electronics? The problem could lie in a faulty solder connection, a bad component, etc.
If you are not confident in opening the amp and troubleshooting it yourself, take it to a audio repairman. Marshall's are some of the easier ones to fix.....

everything was hooked up right. ohms, cables, etc. speaker is fine -- its the head. as i mentioned -- the laney ran PERFECT ALL NIGHT -- AFTER I TOOK THE VOODOO LAB OUT OF THE LOOP. the marshall head is running tho except its now got this loud POP when you put it on standby. i've never had ANY problem with either amp
i find it totally impossible to believe that BOTH my amps experienced the exact same problem -- as i mentioned, the only common denominator is the voodoo lab power +2. THANK YOU ALL WHO ARE TRYING TO HELP ME SOLVE THIS -- YOUR HELP IS SO GREATLY APPRECIATED!!
the unreliable AC current solution seems to be a real possibility, cause i'm looking for some kind of common denominator here since BOTH amps were affected on the same night in the same exact way tho if that is so wouldn't my surge protector have popped? the surge protector never popped.
