I'm in need of a PSU for a Klimax Aktive Crossover. The board is a PCB072L7R1. I've not gotten a good response through my dealer as of yet.
This leaves me wondering about the possibility of having someone else repair the power supply.
Anyone have any ideas? Any other approach I could consider.
Power supply for klimax Aktive Crossover

MusicLover, I have already had it confirmed that the KK power supply I will have as an extra from the KK/D upgrade - supposed to be delivered today BTW- will not work. The paper tag on the PS has "MCAS 027/CD12 014060" on it. Makes me wonder if it's the same PS as the CD12.
It is one of the two. I have swapped the two from each unit to narrow down the problem. I get the light on each with the one and no light on each with the other.
If you can't brag about it, call it experience! I switched from 110V to 240V on a dedicated spur. I had read that all Klimax gear had a universal PS that automatically switched internally. Well - not so with the Crossovers. One unit blew the fuse - it still works, the other fuse did not blow and the PS is well...
A group of 7 very small components labeled R_ _ are burnt.
Pics maybe later if and when I have time and access to camera.
I checked about the Dynamik PS but was told none available.

The power supply board should be available form Linn but my suggestion would be to send the unit in for repair. Linn have a flat service charge for all their components and the service charge for the Klimax Tunebox is less than the cost of the part you need. Linn would charge a bit under $700 plus return shipping from Buffalo, NY to do the repair and our store would add $50 for shipping it to Buffalo and handling of the return paperwork, repair verification on return, etc. With the repair Linn will also make sure the audio board is performing to spec and replace it too if necessary. If the unit has to be shipped to Scotland for the repair (rather than being done in the North American repair facility) that shipping is also included in the flat fee.
On the other hand, the part you list sells for a bit over $800 and you have no guarantee that everything else in the unit is OK.
A word of warning, Linn can refuse to repair a unit that has been damaged by voltage spikes, lightening, etc. so this could happen if it was sent in for repair. But I have only had one such unit refused by Linn which was a Genki that was in a house that took a direct lightening hit. All the circuits inside that unit were badly fried by the surge.

Strange, I had the same understanding. is it an very old Klimax filter? Keltik?SaltyDog wrote:I switched from 110V to 240V on a dedicated spur.

It's all about musical understanding!
MCAS 027/CD12 is the switch mode power supply for the CD12. It was also used in the Ikemi, until Linn exchanged it (on late Ikemis) for the slightly simpler Genki power supply, labeled /G.
Linn should certainly be able to replace this. I'm unsure about the voltages, probably they are higher than the low power Dynamik supplies, which is the reason why you can't use them. If they were similar, it could probably be used if you adapted the wiring.
Since Linn are releasing the high-power Dynamik for the 2250 and 5125, I am wondering why they don't adapt the low-power version to the CD12 and Klimax filters. Shouldn't be too difficult and I wouldn't it be cool to have CD12/D?
