No sub woofer output or very little


Your sub amplifier is detecting an overdrive condition and reducing volume to prevent the output stage from burning up. When reduced volume doesn't work, output is cut completely for 10 minutes until things have cooled down.

The amp cut off and is not coming back on


Sounds like you burned out the sub channel usually due to having a sub the draws more watts than the system can push, effectively blowing a capacitor or node within the internal motherboard of the AMP.

Recommend an Ashdown or Fender with a 15" speaker, they will give a good sound, are gig-worthy, and will last. I use a Behringher 120W for rehearsal work, it only has a 12" speaker and thus cannot give a good 'presence', also I have been reliably informed, a lot of custom chips are used in thier amps.
Don't forget, a bass 'E' goes down to something like 60Hz, and a good speaker and amp are a must for bass work

While playing, the power cord was accidentally pulled out. When plugged back in, the amp cuts on, but there is no sound and the led lights for peak and tone selection flash.


You have probably blown a tube. This amp has one 12ax7 and one 12au7 in the vintage preamp. You can try replacing the preamp tubes, but it can be quite dangerous if you don't know what you're doing!

My Fender 212R 100W 2x12 Guitar Combo Amplifier keeps on cutting out. The guy I took it to says there is something wrong with the cylinders? I also could have heard that wrong. I honestly don't know much...


You had best get a second opinion! When somebody says "there is something wrong" means they don't really know the details enough to give you an estimate even. If the amp cuts out sharply I would suspect that: 1. Bad volume control 2. Cracked circuit board 3. Bad solder joint on circuit board 4. Bad jack. These are in order from least to most likely.

When i turned the bass up to high on my head unit my amp cuts out on overprotection, just for a second and them comes back on. why?


go into your settings in the deck by holding down the volume on most models for 10 seconds then change your hpf settings and your lpf settings your bass will sound much better and not cut out. hpf recommended 160......lpf recommended 140.... good luck

Seems to be a noisy fan on mb4210 combo


Could very well be the fan. The motors can cause interference. There may be a solution to get rid of the noise. Some copper shielding tape may help. You could rule out it being a microphonic preamp tube by turning the amp on as normal and tapping the tubes with something non-conductive. If you hear the tapping noise coming thru the speakers while doing this to a particular tube, replace it. With power tubes, the tops of them turn white on the top when they become microphonic, along with plenty background noise.

Crate BT50 Bass amp cutting out with high input.


Sometimes an amplifier's preamp can't handle certain signals/frequencies at a high gain, so they cut out. Bass guitars are especially prone to giving such a strong signal.
I bought an older, nonworking bass amp recently and fixed it just to find it had the same problem. Best solution is to put a low ohm resistor at the amps input, but if you turn your guitar down to half volume it'll have the same effect: should prevent it from cutting out.
