Despite the fairly low count of semiconductors used in your mike, you have managed to find a thermally sensitive serial number. If you want to confirm this, stop by at an electronics supply store (if in the US, Radio Shack for example) and pick up a can of 'freeze spray.'

When your microphone starts to misbehave again, spray the housing (not directly into the diaphragm) and see if it comes back to life. Give it 30-40 seconds since the innards will only feel the cold after some lagtime.
If it does, I suspect the cost of repairing it is greater than the ~$55 US I have seen advertised for this model.
You can always reserve this one for winter outdoor events. - (I know, it's not funny.)

The amp has worked fine 'till now. During my last session the amp made a brief crackling noise and the power went off. I switched the amp off, then on again. The same thing happened a gain, but this time...

Likely either a rectifier diode, a filter capacitor, or the power amp transistor or chip/stick have shorted and failed. Unless you are electronically adept, it is time to take it to the shop as the cause of the failure will not fix itself. DO NOT replace the fuse as additional damage may occur..

My Marshall 4502E Amp switches on fine. However when you flick the STANDBY switch on it blows the 1.3A Fuse every time. Any solutions, baring in mind I have checked all the diodes, resisitors, rectifiers...

I would first check the filter electrolytic caps for shorts...

This is the WAY you work on this problem. Replace the fuse and put a 60 or 100 Watt incandescent lamp in series with the HOT power wire. This acts as a current limiter/automatic resetting fuse and you can search out where the current is going. Old trick we have used for more than 50 years. Also using a Variac to control the voltage can be useful, but the lamp should get you through the problem...

I have a MXL 990 studio mic which I recorded one no longerworks

Are you using the original cable for the mike? In order to use phantom power the XLR connectors have to be wired in balanced configuration. Pins 1,2 and 3 must be wired separately. If you use a cable with 1and 3 connected you could damage the phantom power supply and in some cases the microphone.

2004 yukon horn problem

obviously there is a short in the system probably in the wiring and likely it is exposed wiring. Motion,moisture, and heat would then effect the wiring and cause it too short out at different times and for varied lengths of times. driving your car would cause it to get hot under the hood, so after awhile the wiring shorts and your horn honks. Turning on and off the system causes motion and if it is stuck in a particular position when it shorts than the horn continues to honk

No speach during xbox game

How do you even know you should be hearing speech? It is a very low budget and low-quality game. Thats probably how it is supposed to be.
