24 channel 8 foot long beast with analogue meters and patchbay. Would this
sort of kit be made with convenience of repair in mind. ie props and cable
extenders designed in ? Would it be a 2 man job to get it open and propped
up, then a partial stripdown just to replace meter bulbs ? Would 2 or 3 of
the main channel sections be removable and repairable off site and rest of
the console be useable without bridging cables etc

The internal ribbon cables are too short to allow easy service access to
the modules while they are plugged in. While it's possible to work on
the modules without removing them from the board, you will want extender
cables if you're doing any serious work on them. You can make your own
extenders from ribbon cable & standard (3M) ribbon connectors.

The meter bulbs can be replaced by simply pulling off the meter covers.

Like most modular mixers, you can remove most of the input and/or group
out modules, and as long as both the main master and aux master modules
are left in, the mixer will still work.

The 1600 modules are bench repairable, but you will need interface
connectors and proper power supplies & test equipment. It's a lot easier
to just use extender cables with the console.

Soundcraft still has the complete manual for the 1600 on their website:

Thanks for all that. The desk is in another country at the moment and I
don't know when it will arrive, new owner buying it with some known
problems. When it does arrive here I will go fully kitted up with plenty of
ribbon and connectors.

All you need to do is on this kind of desk is to remove the first four
channel modules. This will give you enough length of ribbon
cable/connectors to externally test any channel strip you care to plug into
it. You do not need any extenders whatsoever. Similarly with the group
modules.

You can also remove each channel module and power it on the bench from +/-
15v and ground via the obvious Fuse Resistors. The only thing missing will
be Phantom and the Insert loop which you will have to short. Best to work
with a schematic in this case though - sometimes grounds may come from more
than one source.
