SOURCE: B212D powered speakers internal amps

Cost by replacing the amps would NOT be cost effective.

In looking at the schematic, assuming there was a voltage surge on input power, possibly the diodes and capacitors in the power supply are damaged if the fuse blew and was replaced.

If the speakers were powered by a different receptacle than the source feeding the audio to these was, ground bounce may have destroyed the first input stage.

You need to give us current symptoms so we can direct replacement of bad components.

I have KB300 keyboard amplification system,power fuse keeps blowing...but no signs of any burns or short in the circuit board...pliz help.


you have a shorted semiconductor device some where in the unit in the power supply or power amp section, they look just fine when they are worthless, there are techniques for testing these devices...I spent 2 years in school learning some of them...go to this website



http://jacquesricher.com/NEETS/ down load and read modules 1-8 and then read module 16, you may at that time have enough understanding on how to work with semiconductors, remember to use anti-static solder equipment and workstation as these devices are sensitive to static electricity..



every time you fuse your amp you are kicking the crap out of your transformer and eventually it too will be damaged, or take it to the shop.

I have a marshall mb150 and sometimes it used to stop emitting sounds for a while but now in the sounds gets deemer and louder every now and then


Hello,

A common issue with Marshall Amps are generally speaking a low resistor value cracked leg inside the power module, just open up the amp and with the amp unplugged from mains check by a little finger movement the big 2/3W resistors and possibly you will find that one or other will have a broken leg, also cold solder joints do this kind of issue, hope this helps...

250W, 8 Ohms speakers on 150W, 6-16 Ohms Amplifier.. What is the effect of this?


If your amp states that it will support a range of 6 - 16 ohms, an 8 Ohm speaker will work fine on it. If the speakers you hook up to it are lower than 6 ohms, it may work until you turn it up, then it will either shut down or burn out the finals. If you hook up a speaker that has a higher than 16 ohm, it will not get very loud, and it shouldn't hurt the amp.

I just wanna check was my little mark 250, older version, ever been opened or changed in any way. I was at the guy that opened it and told me that because of the input power of transformer that is about...


when using amps,, you can't go by the number of the amp to determine what wattage the unit puts out, after checking on this amp,, the white marks that your seeing on the cable, is probably just some of the thermal paste that you apply to any heatsink or CPU ,, nothing to worry about, now as far as the wattage,, here is what they say about that amp, so there is a difference between the 4 and 8 ohm set ups
The Markbass Little Mark 250 bass amp head is a high-quality bass amplifier with a solid-state preamp and an analog power amp. The Little Mark 250 delivers 250W of power into a 4 ohm cabinet, or 150W into an 8 ohm cabinet. This Little Mark has a 4-band EQ, Markbass' VLE (Vintage Loudspeaker Emulator) and VPF (Variable Pre-shape Filter) filters, as well as both Gain and Master volume controls. The front panel accepts both a passive or active bass 1/4" input, as well as a balanced XLR input for acoustic bass pickup systems or a microphone. On the rear panel you'll find a Neutrik Speakon combo jack output that accepts both Speakon or 1/4" speaker cable as well as a second 1/4" speaker out jack. You'll also find a balanced XLR out, unbalanced tuner out so you can tune as you play without passing your signal through pedals, and a Send and Return Effect loop which saves you from losing your signal if one of your pedals dies or a cable in the chain gives out.

I also need a Braun Paximat Lamp bulb 58.8394AMX


What is the description of the lamp? Braun's current catalog numbers for lamps are 80231 for the 150W 24V and 80232 for the 250W 24V. If you need a different lamp you should bring the old lamp to a camera store and let them look it up from the bulb manufacturers.
