Kora Cosmos Reference

Health and Prosperity to you all in 2018.

I recently (December 2017) acquired two as new/ unused Kora Cosmos reference mono blocks for my sins and have since read the good the bad and the ugly. However, I would like to check the bias and after numerous efforts to locate the service manual or bias procedure on the internet have drawn a blank.

Can anyone help ?

Thank you

Hello and welcome to AC, vantage. I can't help but if you post your query to as many audio forums as you can find then hopefully someone will respond with the answer you seek.

I already search the Google, this manual is unobtainium in PDF, the maker are French, no site, no factory, they gone in 2007:
La société KORA ELECTRONIC CONCEPT a été radiée le 20 juin 2007.

I would suggest email the Stereophile tester Michael Fremer for Bias instructions:

Welcome to AC.

The Internet Archive Wayback Machine has a lot of Kora info. Clink on links to see screenshots, most links work.
If US sources fail then calls or email to old Kora distributors in Europe may work.

Or call the number below and see what happens:

Thanks to all you responded,  appreciate it and will follow up on the Internet Archive Wayback Machine. that's a new one for me!

I did via the usaudiomart find a guy who had previously owned and sold and he mentioned
 the bias instruction in his ad,  after joining and making contact he sent me what he had and I will post or send if requested.
see example



Never give up !
