Need: Luxman L-560 Schematics

[sperlst]

Hi,
I am trying to help a friend to fix the Luxman L-560 unit he owns, for that we need Schematics.
Any chance someone here can put his/her hand on it?

Cheers,
Shay

From a certain period in the late 80's there were a few Luxman models for which no schematics have surfaced until now - go to
https://www.diyaudio.com/community/threads/luxman-a373-d375-t353-integr-amp-cd-fm-tuner.193274/
Obviously the L-560 is one of this models - even under
https://www.hifiengine.com/manual_library/luxman/l-560.shtml
isn't mentioned a service manual.
Interesting to know would be the reason therefore.
Maybe it have to do with this: "In 1984 Luxman became part of Alpine Electronics" - go to
https://en.wikipedia.org/wiki/Luxman

thanks for the detailed explanation !

maybe one of the members from Japan can find out in his own country, from where this in Europe not released service manuals are available.
E. g. this member:
https://www.diyaudio.com/community/members/shinja.87307/
send a PM.
Maybe he can contacting this nearly 100 years old electronic/audio magazine from Japan

thanks @tiefbassuebertr !
nice suggestion, unfortunately since I am a new member here, I can not send any private messages to @Shinja.
Maybe tagging will work.

Hi@sperlst
Have you found the service manual for L560 or L550X?
I'm struggling to set up bias on my own L560.
Do you have any information about the bias adjustment and voltmeter read values?

Hi @MarkusDedalus,
We have found nothing, by now my friend gave up and got himself a new system.
I hope you will have better luck.
