Emax

Are you sure it isn't just the key and switch contacts?

Subject: [emax] Emax II Service manual plea

Hi all

I have an Emax II Turbo keyboard which has developed an intermittant fault. 
Periodically, some of the keys fail to trigger and this has now worsened so that certain number buttons don't respond either. Now I believe that I must have a failing Scanning chip in the Emax somewhere, but sadly, I don't know how to locate/replace it. Does anyone here have a service manual they would be willing to sell/copy?.. or could anyone advise me which chips need changing and their locations?.. 
I would be prepared to pass this on to a reputable repairer/engineer(I am London based), but sadly they seem to be few and far between these days.. so any recommendations there?.. 

Help
