Linn Sizmik sub amp repair - need schematic

[len_scanlan]

Hi Everyone,

Just wondering if anyone out there has access to a schematic for the amplifier module in a Linn Sizmik subwoofer?

I recently bought the amplifier module from one of these, and luckily pulled the lid off to inspect it before applying power.

The SMPSU driver IC has burnt out (smoke residue all over the PCB!) and probably one or more of the driver FETs are shorted.

The PCB doesn't seem to have suffered too much damage, so I'm hopeful that it's repairable. However it is a multilayer design so I really should have a look at a schematic first rather than just replace the burnt out components and hope! If a track on an inner layer is burnt out then I'm in trouble..

The unit dates from 2000, and has both speaker and line-level inputs (The current units on the Linn website seem to have only line inputs).

Here's hoping someone can help!

Thanks,

Len.
