I had a previous post with my MG102CFX amp cutting out after 5 to 10 minutes of playing. So i replaced the Fan under the heatsink and it worked greats for the last 2 or 3 weeks. So i bought this Zoom G5N mulit effects processor, and it was working great on the 102, for the last week or two. But last night the amp just cut off again. Head phone jack still works, pretty much the identical problem i had before i installed a new cooling fan. Only this time powering the amp on and off, won't bring the speakers back to life. Amp sat all night and still no sound through the speakers, but the headphone jack still works. Anyways after that amp cut out, I plugged my Zoom G5N into my MG30CFX, was playing along great untill the sound just went very quite and twangy sounding... head phone jack still works as normal on that amp as well.... Not to sure what happened or did this G5N pedal destroy both my amps? lol. When i have time to take them both apart, i will look for cracked solder joints or any burnt marks any where i guess, but is there anything else I should be looking at here or trying to test, i can't really think of what might be wrong now?
