Hi Richard,

The MS600 is fairly simple to get into...

1) Remove the four rubber feet
2) Remove the slide-in covers that hide the rack mounting points (they slide out - downwards - hence removing the feet)
3) Remove the top four T25 bolts that hold the outer top cover (one in each corner - hidden by the slide-in covers)
4) Undo the umpteen bolts that hold down the inner top cover

1/2 hour later and after a stiff drink, you're finally inside the unit...

Re-assembly is the reverse of disassembly!

The unit has an ECM40UT31 switch-mode PSU, no batteries as it is effectively a cut-down ID41 and analogue output card.

Hope that helps everyone out.

Cheers,

Steve
