A signal tracer is needed, together with the signal source.

Sodering Iron or similar

We need to know more information. When you are asking for a schematic, it means internal wiring and circuit diagrams. It has mostly nothing to do with wire color codes.

Where is the serial number on a crate amplifier


Real basic owners manual is here:
http://www.crateamps.com/pdf/manuals/CA6110DG_OM.pdf

Look at the chassis, or pull a part number off the original speaker to match speaker and back cross reference to the amp versions that used it. The OM is at least good enough with the block diagram to allow it to be serviced easily enough.

I need the schematics for a Marshall MG-10KK guitar amplifier in order to repair it! I'm a good technician but I don't speak english very well... rsrs Thanks!


Most of the problems with the small guitar amps are blown power amp chips. They usually use chips like the TDA2030 which look like a power transistor.
Most other problems involve broken connectors, bad solder joints or cracked circuit boards. The power supply area is so simple one doesn't need a schematic for that part which is usually just three terminal regulators for +/-15 volts. Schematics are often hard to find.
Try this site, although this is a different model, much of the schematic will likely be the same.

Acoustic Image Contra series II - No audio passing through preamp - Need schematic and parts list. The amp was overdriven due to bad ground in guitar. The amp powers up, but no signal is heard.


I decided that without a schematic and parts list I shouldn't even attempt to repair it. I had taken the cover off and disconnected the control board from the amp. When putting it back together to return to owner, I noticed the plug and socket for the control board did not go together properly. After a little maneuvering, I managed to get then joined, and just like that the amp was working again. I suspect that who ever had repaired the ground on the guitar had opened the amp up as well, and just didn't get it back together properly. The amp wasn't really damaged, after all.
