Help downloading from Hifiengine website

No help for my Kenwood KA-70 ???
I do have the two page .pdf schematic, but what I need is the full service manual

PS Something strange happened a couple of days ago: Instead of receiving the usual "unrecognised ..." message, I was allowed to log in to a page where even my forgotten ancient e-mail address (decades ago) was displayed. Yet, nothing else was active, and nothing was sent to a new e-mail address I proposed.
Today, business as usual - ''unrecognised etc etc "
 
Still down on 5/4.. Get the following when selecting a pdf for download after logging in. An upgrade (I'm assuming!) to the download system is a positive step I hope.

"Sorry, but the download server is temporarily closed while work on a new download system is completed."
