930turbo Posted January 9, 2019 Share Posted January 9, 2019 Hi Kiat , fellow members of this forum , In the old Princess C5000 was Solen caps used as well ? It would be easy for me to open mine and check but I’m afraid to do so because I might damage something. Thanks in advance, 930 Link to comment Share on other sites More sharing options...
Kiat Posted January 9, 2019 Share Posted January 9, 2019 (edited) Hello 930 The crossover is directly behind the terminal plate. Once you remove the plate, the crossover could probably be held by a screw. Simple remove the screw and the crossover can be easily withdrawn from rail. It is quite likely your crossover uses Solen Capacitors. Solen is just a rebranded SCR capacitors, Made in France. SCR is a major manufacturer, supplying parts to the French TGV. SCR also rebrand their capacitors for many other "High End Capacitor" brands. I know I have seen them changing printer heads and the production process continued. Do not worry about your Solen Capacitors or SCR capacitors. But be aware that there are many Solen knockoffs selling from Asia. BTW, if anyone chooses to use Solen, be aware Solen also have some capacitors Made in Canada and they are much cheaper than the French made ones. I have not tested them and do not know how they sound. I heard a rumour and this is just a rumour that you can buy "Solen" capacitors that are Made in China. I am sure Solen would be interested if anyone pick up some of these "Solen" capacitors. Edited January 9, 2019 by Kiat 1 Link to comment Share on other sites More sharing options...

I would be very surprised if a C5000 used any solen "knock off" caps Kiat! 1 Link to comment Share on other sites More sharing options...
Kiat Posted January 10, 2019 Share Posted January 10, 2019 Oh no, Definitely NOT. The knock offs are only recent, about 5 years, I believe. Link to comment Share on other sites More sharing options...
VanArn Posted January 10, 2019 Share Posted January 10, 2019 I have come across capacitors that were fitted to a crossover network ( to improve it !) , that had an almost identical appearance to the 'Solen' polypropylene capacitors. They were marked as 9mfd, + - 5% Type PB900, 150 v AC 250V DC. They measured 3.8 mFd and tested as bi-polar electrolytics: faulty ones to boot. There was a giveaway visual indication in that the encapsulated ends were coloured red instead of light grey. 2 Link to comment Share on other sites More sharing options...

Counterfeiting plastic caps would be more profitable than counterfeiting power semiconductors. And, in that sense, I've seen counterfeit $2.50 MOSFETs and $4.00 BJTs. A $10.00 capacitor could be a very lucrative thing to counterfeit. Link to comment Share on other sites More sharing options...
930turbo Posted January 10, 2019 Share Posted January 10, 2019 Hi Kiat , Thank you very much for your reply . On the old Duntech website , I remember SCR Caps were on sale . Best regard , 930 Link to comment Share on other sites More sharing options...
Kiat Posted January 10, 2019 Share Posted January 10, 2019 Yes but I think your caps would still be fine. We may have a new reseller in the Philippines soon. Link to comment Share on other sites More sharing options...

Solen also made capacitors with red ends, back when Duntech was in Adelaide at least. Link to comment Share on other sites More sharing options...

The value of the capacitance, the type of capacitor, and where it is put in the circuit. ..... is 10,000x more important than the "brand" or price of the capacitor. 3 Link to comment Share on other sites More sharing options...

Yes I totally agree with you!, but when you have accomplished that, it’s nice to put nice quality caps in. Link to comment Share on other sites More sharing options...

I am not sure the current owner of Duntech would be much help as the Baron's were made a while ago now, I have googled to hell and back and cannot see an example of spikes on the Baron models from above the speaker base. I can only imagine the spikes were an ad on for standing on carpet and if there is a recess for them under your speaker foot then just improvise... my 2 cents.

Elsal Posted January 23, 2019 Share Posted January 23, 2019 Hello to all, my first post here. Recently i acquired a set of Dunlavys SC-II and i am quite a fan of the "house" sound. I am keen to upgrade to a bigger model and used Duntechs (princess, baron) come by much more often here in the EU. It seems that most of Duntech speaker units (Morel, dynaudio,..) used foam suspension instead of rubber which means they will almost definitely need replacing at some point (in this respect i was lucky with my SC-II, their rubber has minimal signs of deterioration). --> Is there any reliable stock of units in the EU, or at least proper suspension materials? --> From a technical point of view, is it better to replace a unit with a new/used in better condition or professionally repair the suspension and retain the matching of original parts that Mr. Dunlavy did during manufacturing? Of course, if there is any owner in the EU that wishes to sell, please feel free to PM me! Elias Link to comment Share on other sites More sharing options...

Silver Audiophile Posted February 2, 2019 Share Posted February 2, 2019 Check out the hardware. Vivaldi CD player system, Dan Agustino’s preamp, Audia Flight Strumento no.8 monoblock and Memphisto turntable. Now, that's how one should review a speaker!
