Servicing a Midas Venice

I finally got round to properly opening up my local venue's old Midas
Venice with a view to replacing a few scratchy and intermittent pots.

I had a rough expectation of what to expect internally having seen
inside more than a few consoles.

I was however utterly stunned by this one.

Those familiar with the art of M C Escher

Would immediately recognise his influence.

How about connectors mounted on the opposite side of the board that
faces you for example ?

The way it's built, I can only assume they must have some kind of
assembly jig, because no way could human hands reach some of those
connectors once the pcbs are bolted to the panels.

My suspicion is that the only possible way to go any futher is to
unscrew EVERY connector on the rear connector panel just to be able to
access the connectors that link them to the channel pcbs, so as to be
sure of re-connecting them properly on re-assembly.

And this was done largely AFAICS so that 'everything' on those pcbs
could go through a flow solder machine. Have they never heard of masking
certain portions of a board so as to have some components on the side ?

I'm stunned. And there's other overkill stuff too.
