INTRODUCTION:
For many years we had a pair of speakers designed and created by the multi-instrumental, progressive rock musician Bo Hanssen from Sweden.
Sure there are great loudspeaker systems made by "backroom boffins" who only deal in the technical details of loudspeaker creation but any musician wants that "sweet" sound and in Bo's case, if you can't find it then you produce it yourself.
Bo had the philosphy of creating high-end loudspeaker systems but at affordable prices! Depends what you call affordable, these were still VERY expensive systems in their day.
Sad about the choice of trade name (SINUS), perhaps it means something different in Swedish!
SINUS was Bo's early venture into "better sounding" loudspeaker systems before morphing into RAUNA of Sweden, then Bo went off on his own (creative artist differences with his partners - happens a lot in the music industry) and was the driving force behind Opus-3 and other systems such as the CaveRex, Okko, Huggin & Munin - watch out for these names, loudspeakers that will astound and surprise!
As luck would have it, Bo was getting set to ramp up production and it all ended very suddenly with his sad passing away in 2011.
If you find this sort of information fascinating (I do!) then take a look HERE for more nitty gritty (no dirt band) on Bo Hansen and his exploits in the world of audio.
So what happened Russ? (I hear you ask, head cocked to one side and one eye closed!)
I was offering our complete A 103D system but not much interest once people found out how much it would cost to have them shipped! Bo made the cabinets extremely sturdy and the result was loudspeakers that felt like they were made of steel!
I waited and waited but the "right person" didn't appear from the mists, I have now decided to use these lovely old A 103D's as a component farm - sad but at least someone else can proudly say "Mate, I have Bo Hanssen inside my speaker system ... listen, you can hear him playing!"
So hear we go with this SPARE PART for the SINUS A 103D (or your own custom crossover design) .... Read and enjoy
SINUS (Bo Hanssen) - A 103D Loudspeaker System SPARE PART ONLY
Very briefly, the A 103D was rated at 100W RMS per channel, presenting a 4 Ohm Impedance Load to the amplifier
The configuration is 3 way - Bass, Mid Range and Tweeter.
The sound was "nice", I liked it very much but not just from the sound aspect but here was a loudspeaker designed by an accomplished musician! I like that ...
I did not sit down and work out the crossover design, my thought was that someone wouldn't be copying the original crossover but instead designing their own.
ELCAP - Bipolar Capacitor
Made in Europe (I strongly suspect RIFA "had a hand" in these!)
There is no way in this world they were imported from Asia
Circa 1970's
Part: Bipolar Capacitor
Value: 100uF 50V
Black body with Red/Brown end caps
Axial leads
DIMENSIONS:
41.5mm Length x 15.75mm diameter
Leads are 40mm length x 0.75mm diameter
COSMETIC CONDITION:
CLEAN
Undamaged in any way
Carefully removed from the cabinet. The crossover network is actually mounted directly onto a section of particle board with all wiring being made point-to-point and also using two tag strips. Everything was secured to this wooden base using wood screws.
The leads have not been cut, exactly as removed from the cabinets.
TESTING:
This capacitor sits across the Woofer terminals in the SINUS A 103D system
Although used in many high end loudspeaker systems of the day (Wharfedale is one of many) ELCAP's have an unfair reputation amongst some "know it all's"! Like ALL electrolytic capacitors, over time and depending upon the environment they have been kept in plus the operating conditions, they go "out of spec" - sometimes wildly, become "leaky" (cannot hold the charge) or even some becoming completely useless for their original purpose. This is a fact of life for an electrolytic capacitor and it is not limited to ELCAP's!
For this reason I have tested both of the capacitors and the results are:
#1 Bipolar
Vloss 3.5%
117.6uF
ESR 0.95 Ohm
#2 Bipolar
Vloss 3.2%
102.6uF
ESR 0.97 Ohm
I have marked each capacitor on the Red/Brown end cap so that if one is preferred over the other, I can supply the requested capacitor only.
These capacitor is now packed into a sealed, labelled, plastic packet to preserve the condition.
*** Where the photograph shows multiple components, this advertisement is for ONE capacitor only - not all that are shown! ***
