Hello guys.
I have an Ashdown MAG300 EVO ii bass amp on my workbench. It was stacked together with other music gear in a small storage room - not the best idea. I got it to work now but it does not sound as it should. Cranked up all the way, it does not get to 300W. And I had it once before so I have an idea about how it should sound.
I got the service manual for the ASHDOWN ELECTRIC BLUE MAG which is similar but not the same.
For example: The compressor is missing in the schematics, the Electric Blue has a few different op-amps than the MAG300, also a different IC numbering, etc.
Any idea where to find the correct schematics?

You can write to Ashdown stating the model number and a small description of the fault.
They will send the schematics.

Ashdown sent my several schematics for the MAG300, including the one for the EVO II.
I cannot figure out why it does work but not as loud as it should...
when I plug in a cable and touch the tip it sounds really loud. As soon as I plug in a bass guitar, it doesn't.
Also, the VU-meter has stopped working. The driver for the VU (LB1413N) seems to be ok, it moves when I touch ground and pin 7.
I will replace IC1 LM833 with a NE5532 (that is what I have on hand), see what happens.
