Am the new owner of a pair of Jamo MFB 300 active speakers.
Being made in 1978, the speakers need to be updated with new electrolytic capacitors and relays. Then they should be calibrated with correct bias for and output level to the 3 output amplifiers. And the feedback loop for the speakers sensor should also be checked/calibrated.
There is an owners manual with diagram and component value. This one I have.
Measure-points and values for the data mentioned above are not in this manual.
Jamo was originally a danish company but has ceased. I think 14 years ago. The name is owned by Klipschgroup and they still produce loudspeakers, now made in China.
Do anyone here have any information of the data I am seeking or can possibly point me to where it can found?
I hope this information is still available somewhere.

I found a Dutch website with forum that seems to be about MFB speakers. Maybe you can find help here? With a good translation program, the Dutch language should not be a problem:

Hello Azrael,
Thank You for Your answer. I appreciate that.
The MFBfreaks HP is known to me, since I have bought service of a pair of Philips MFB 587 by them. They do a good job and the idea is to let them service the electronics of my Jamo speakers if/when I get more information, as written above.
The webmastger of the HP owns a pair Jamo MFB 300 himself and is also searching for this info. I am in dialog with him.
Kind regards
