Help downloading from Hifiengine website

Could someone kindly provide the owner/service manuals for the following models:



KENWOOD AUDIO TIMER: AT-52B

KENWOOD REVERB AMPLIFIER: RA-90IIB

KENWOOD GRAPHIC EQUALIZER: GE-100IIB

KENWOOD TUNER: KT-51B

KENWOOD STEREO CASSETTE DECK: KX-51B

KENWOOD INTEGRATED AMPLIPIER: KA-51B

I understand it's a big request, but as you all know, these vintage models, and the source, HiFiEngine, is currently denying access to everyone.
 
With hifi engine, when you are in, you're in. And whey you are out, you are locked out in perpetuity. And the site owner hides, so there is no way that a human can help resolve being locked out.

The site even blocks access to the "contact us" page.

Sigh.
 
I managed to get back in via the contact page after they deleted passwords so it can be done. Had to track down my email address I used for registration. I received a password reset link within 5 hours. Probably would not help if locked out.
 
I have a user name and password. But it does not give me the opportunity to enter them. If I try to access a manual etc it says:

"Sorry, but an error occurred loading the page.
If you are using a proxy or VPN, please turn it off to continue.
If you are continue to receive an error, you can report the error using the form on the contact page.
Error Code AS 51561"

I don't use a proxy or VPN, and I have no idea what Error Code AS 51561 means.

And when trying to use the "...form on the contact page" it says

"To prevent form submissions by bots, this form is not accessible to IP addresses in Data Centers:
46.33.139.174 (ICUK Computing Services Limited)
If you are using a VPN, please turn it off and reload the page to continue."

Data centers? So anyone using an Industrial Grade ISP such as https://www.icuk.net/ (which I've used for a decade) is locked out, Just yesterday I organised a VOIP connection by phoning them, instantly talking to a technical guru (no select number x, select number y) two phone rings and someone who knows what they are doing answers.

I've given up with hifi engine.
 
Hello everyone! I'm in need of a little assistance. If anyone here has an active HiFiEngine.com account, could you kindly help me download these two files from the following link: https://www.hifiengine.com/manual_library/sansui/au-111_vintage_1999.shtml (for Sansui AU-111 Vintage 1999)? I would greatly appreciate your help. Thank you!

No?

I have an account, but your link was dead to me. Perhaps after many years, my own access has been blocked
