here is a reply to my email last week to Chris Whitehead so we can expect a new posting

Hi Jonnie,

I am hoping there will be a new posting explaining how to obtain an upgrade
in the UK. We strongly recommend and always have done that you order the
disk from you local dealer as they will me made and tested by Technics UK.

This will hopefully be explained more in the new posting soon to go up.

Best Regards
Chris Whitehead
