Probably smoked the output IC(it is the chip mounted to the heat sink attached to the fan) which can be purchased from marshall directly or from one of their service centers. Also P-H216 sold at tubesandmore.com should work. No soldering required. Look at that IC(chip) to see if it looks burnt or has a crater on it which would indicate that that is indeed you bad component.

What one? Keyboard or Piano?


That would depend on what you want to use it for. Assuming you mean a real piano, it's not portable, it can't be used with headphones for silent practice, and it will need periodic tuning and general maintenence. However, no electronic device is actually going to sound like a real piano, and no action feels the same as a real piano. Keyboards, on the other hand, can be played in different locations, have a larger variety of sounds, and are cheaper to maintain. As a pro musician, I own both. Actually a number of different keyboards, but only one piano

Plug the guitar on the "power amp in" jack near the "presence" knob.
If you get sound, you have a problem on the preamp. If not, it´s probably on the power amp section.

Mg100fx just stops making sound until its turned off for a few seconds then turned back on


This looks like an overhaeting problem at fiirst glance. This shouldn't happen however. Have you had it long before it started failing? Doe it happen every time you play it, and also at low volume? If so, all I can think of is having it checked out by a technician.

Korg Microkorg XL Vocoder Not Working (No Sound)


Check the mic and connections all through its input into the unit. I would check the cartridge of the mic for continuity for the reason that (I think but not 100% sure) on this model, I think there has to be sound at the mic or it does go silent in vocode mode. This is how it digitizes the mic and keys together. The played keys cannot put onto pitch the sound it is NOT picking up at the mic. I think there is a problem with the mic.

My Peavey vk100 head is running through a Carvin Legacy 2x12 cab. On the clean channel there is an inconsistent popping sound. It will happen loudly for a few seconds, and then not at all for a while, and...


You may simply be overdriving the clean channel and causing it to "flat top" . See if it occurs when you back the gain down a bit. New tubes PROBABLY will not help and be a waste of money. You may be unconciously playing harder during the popping episodes. You cannot hear level variations smaller than about 3 Db BUT the electronics will sense much smaller variations. You could gently tap the tubes with a lead pencil to listen for any pops... NOTE: tubes can be slightly microphonic so some sound from tapping is normal.


Yes, a cable can be noisy and not show itself when using intentio0nal distoprtion... try another to verify it is not the problem.

Marshall MB4410 - Dies and comes back to life every few minutes..


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.
