https://elektrotanya.com/keres is where I sometimes get my service info (among other sites).
Screw that hifiengine crap site..... and it's sister site vinylengine.
It's not ok to say that as a lot of the documents found on electrotanya if not all of them come from mirroring hifiengine.It's pure information theft we enjoy now...But a lot of the info you find on hifiengine is unavailable on electrotanya because of the ban practice.
And the vinylengine forum's information used to fix my Duals!
Hello everybody,
can someone with working Hifiengine account download and send assembly/installation info for Rational Audio Z1 amplifier from this url:


on web page:

https://www.hifiengine.com/manual_library/rational-audio/z1.shtml ?

Or does someone have some information, schematics etc of this amp?
I cannot create account there as the registration is closed now.

Thank you very much for any help and best regards,
Karel Klapka
The second link https://www.hifiengine.com/manual_library/rational-audio/z1.shtml works.

(The question mark at the end of the line of the link in the original post is wrong)

(First one not, because the server does not alow it.)

The text for search is "Rational Audio Z1" reveals the page as first "non Ad" link for me..., that is the second from bottom end.

Thanks a lof if you manage to download and send it...

Do you need all the text in the manual or just the circuit diagram?

There are lots of pages like this:

Hey all, from the us, on mobile, and no VPN, and I'm still having the same registration issues. If anyone can grab me the Jvc KD-D5 manual, I'll be on your debt
In hifiengine the search of JVC KD-D5 gives nothing. So I downloaded JVC KD-D50. Hope that is what you were looking for. The file size is little above 10MB and diyAudio says file too large to upload. I Dont know how to proceed.

Hi, appreciate the help from folks sharing documents for those of us who were not a member to the other site before and have no way to access it now. If anyone could be so kind, I am seeking this service manual:

Pioneer CT-F6161 - https://www.hifiengine.com/hfe_down...eer_ct-f6161_service_art-100-0_en_low_res.pdf

There are only small fragments of the logic board floating around elsewhere, and a few documents in another language.
Here are three downloads. Pioneer and Sharp manuals are too large so giving links of third party download, which is time bound. I take no responsibility of it.

A humble request. Since you all are new members kindly remain active in forum and help the community in your individual capacity like fault finding of audio equipments, donations to forum, guidance, product information etc.

2) Sharp : https://filetransfer.io/data-package/oZWhZcnI#link

Thank you so much, Hiten! I am brand new to the hobby and am only just getting into the restoration scene of them but I will always love the quality and craftsmanship seen in a lot of these sets from the 1970s-80s compared to the generic players I've only ever had before. The sound is terrific once restored. Will do my best to be more active here!
