The OP appears to have good understanding of what's going on here, so why not just add a rotary 2 way switch to the gram input socket, use 2 inline "Y" series 500V DC isolation caps, fit the switch to the rear card cover panel, ensure the mains neutral lead is connected to chassis and get going?!
Perhaps: 1: This is all too simple 2: I'm missing something here 3: I've lost the plot!

Hi Edward
Thanks for your sanity check.
No you haven't lost the plot, and what you suggest is what I had hoped I could implement on the outset.
This thread has been a real help to me and I am in a much better place than when i took delivery of this a week or so ago. In my career I have never seen this type of live chassis set up or lack of earthing arrangements so to implement my desire to input a 'line in' safely is requiring this journey for me.
A recent poster has identified that the 'common' line on the cartridge is chassis grounded and as such is live.
This is something I wish to resolve safely before I am able to achieve my goal. Although this may seem like the tail wagging the dog, until I remove the live element of the chassis I cannot perform my mod.
So all posts are entirely relevant, and very much appreciated.
Your suggestion of isolator caps is another education for me, I haven't fitted anything like this before, so will this give electrical isolation from a potential 240v fault on these lines?
