Amps have fuses inside. Check them if they are blown. After replacing, if it keeps blowing, then you have a short that needs to be fixed. Good luck!

SOURCE: Amp goes quiet after working fine for about 15-20 min.

If you are not a tech, I suggest you send it to one. If you are, after signal-dropout spray output transistors (one at a time) with component cooler (freeze spray). If still no results, go to the other transistors & IC's. Chances are that will pinpoint faulty component.

The preamp section has a problem. It could be anything in the preamp but is OFTEN the input jack itself. They take a lot of abuse.

Also the insert jack contacts that forward the preamp to the power amp if no external FX are used can go bad.

Additional things are circuit board cracks caused by rough handling and also controls that have had the knobs mashed in which can destroy the potentiometers they are connected to.

You should NOT under any circumstances connect an audio input lead to a speaker output jack!
The RCA jacks you are trying to take output from ore "pre fader" which would be solid "line level" and not controlled by volume controls. Tap off the INPUT to the amp... you should be using balanced lines for the interconnects. RCA jacks are unbalanced lines. You can drive several inputs from a line level output of a mixer for example using a splitter cable.

It is likely that there is a failure of one of the amps in the unit. It could be a cracked circuit board, bad solder, bad volume control, or a bad compnent in the power amp section for one side. HOWEVER something does NOT compute here as you can't connect more than one speaker to a 15 Watt Crate amp... Maybe you have two of these amps.

Hi I have a marshall haze15w amp and stack, the problem seems to


There are many models of Marshal amps icluding 15Watt types.

First thing to try is to see if headphones have normal volume. If they do, then the headphone jack switch that connects the speaker is LIKELY bad.

If the headphones do not have any volume, LIKELY causes are:

1. Fried output power amp

2. Volume pot is broken or has bad solder joints to the circuit board.

While playing, the volume cuts up and down in all the channels.


Fiirst check if your input connector is bad. Move the cable right at the connector and see if the volume jumps... HOWEVER before doing that even, verify your guitar is not the problemm using another amp.

If it is definetly the Marshal, it will likely need servicing.

It could be a bad volume control or a cracked circuit board.

The volume control is not working... even when the volme is "off" it is still on


Chances are the resistance element in the volume control has broken. This is COMMON if the control knob gets smashed some way.

A less common thing would be broken solder where the control is soldered to the circuit board. This would be obvious once the board is accessable.

Servicing involves removing the chassis and replacing the potentiometer.

Problem of marshall g80rcd, volume drop when i play


It sounds like your volume control is dirty. You will have to disassemble the amp enough to get access to the volume potentiometer which is soldered to the circuit board. There will be a square hole in it that you can spray some contact cleaner into the control. Use only contact cleaner as anything else could damage the control. Use a small squirt and rotate the shaft. If this doesn't solve the problem you may have to replace the control. While you have it apart, examine the solder side to make sure all the solder joints are perfect especially those on the controls. A bad solder joint can also cause the same problem. Before you take the amp apart unplug the power with the amp on and the volumes turned down. This will discharge the capacitors so it will be safe to work on. I hope this helps.

High pitched squeal when the input jack is used.


Sounds like your master volume is turned up too much. The channel volume will make the squealing go away(caused by high gain and humbuckers). The best thing to do is dial in your favorite presets and change the channel volume to the correct level with the master volume where you usually keep it. I use my Spider Valve at master volume at about noon and the channel volume between nine o'clock and noon. Let me know if this does not solve the problem......

Crate flexwave 120 head sound cuts out


You have a broken solder joint. You'll have to disassemble the amp enough to get at the soldered side of the circuit board that the controls are mounted to and touch up any suspect solder joints. Just be sure to resolder only the joints that were originally soldered or need to be soldered. Hope this helps.
