Allen and Heath Mixwizard schematics/service
Hi,
I've got a mixwiz 16:2 with a few problems - I'm (still) waiting for a service manual from Allen & Heath, but until I get hold of one, has anyone seen a schematic online anywhere? Many thanks John |

Many thanks John hello, I've just fixed some problems on a wizard 16.2 one week ago: Loss of bright & level on tracks inputs: change electrolytic condensers (47µF 63V) loss of level on track input: repair broken copper track (a little difficult to see without magnifier) hope it help you best regards Francois Barvec |

I have no input signal on my first channel, changed the capacitors yesterday and I'm suspecting a broken track. Can you point me in the right direction where it might be broken? BR Anders |

Can you point me in the right direction where it might be broken? No, but a meter set to continuity test will help you. Stab the solder joint on each end, see if it beeps. If it doesn't, stab one solder joint and a spot in the middle of the trace. Cracks mostly appear around pads, and mostly in places around things like pots and connectors where the board flexes during normal use. But sometimes you get some really weird cracks in odd places due to manufacturing defects that take decades to show up. Or due to boards being deformed in place. --scott -- "C'est un Nagra.
