SX-KN400 service manual/help

[lefetylorant]

Hi,

I got a Technics SX-KN400 which is not working for free.
I want to repair it but I have not found a repair manual to download and I do not really want to pay a lot of money to get one because it does not worth it for me.
First I checked the PSU section and the 20 volts are there, fuses are not blown.
Then I dug deeper, and noticed that there is something missing next to the amplifier IC (I gues it is a voltage regulator, but which one?)

So yeah if you have the service manual for this keyboard please send it to me or maybe if you have the keyboard itself I would not mind if you would check the number of the missing component for me.
Thanks,

Hi,

Thanks for the reply!
I have not even found an SX-KN450 just the SX-K450.
As I see it has quite a little in common with my keyboard.
It seems that the SX-KN400 is part of the KN200, 220, 440 family, but there's no available service manual, just the user manual.
I've searched for it everywere, but no luck yet.

*Hi
found in archive
KN200,KN400,KN600 : launched in 1989
so the same family, the kn600 is 2x10w and the kn400 is 2x5,5W
did you look at
www.technicskeyboard.com (difficult site)
www.keyboarder-forum.de
can you see some info on the amp Ic or on the print by the missing component.
good luck and stay save
