Question about Marshall MB4410 Bass Combo Amplifier
After about 30 minutes of playing, the amp started to lose volume and stopped all together. Two minutes later it will start again but do the same thing over and over...Every few minutes it'll come to life and then die while the light stays on. Any ideas?
Our bassplayer had the same problem with his mb4410. As it turned out, the fan was not working when the amp got hot. It did turn when cold - go figure! Swap the fan for a good quality (Pabst, Sunon) 80mm pc fan with 2-wire connection. Three or four wire fans will not work w/out modding. See your local pc guy and ask for an unregulated, silent 24/7 fans. He will know. Our bassplayer sold the P.O.S. while still in warranty. HTH.

Testimonial: "Thanks for the reply."
Its a possibility that the amp is overheating, and for that reason the thermostat opens, when it cool down it close bringing the amp back to life
