    Yes, I was able to find everything.

    Kashke has been aquired by Bourns. I contacted Bourns but their service does not really want to help – not even with datasheets. Then I found PMEC. As for Kashke 049.752, this is the direct replacement:

    PMEC 102/Ve 18m 1,0 A

    https://shop.pmec.cz/index.php?page=details&cat=2&prod=1062&alt=102/Ve%2018m%201,0%20A

    Kashke 049.769 is a customized component – which does not exist. But I sent mine to PMEC and Josef from PMEC did all measurements and they could produce a replacement for me. Technically, it’s

    102/Ve 18m 1,0A, too but it has some isolation and the winding is reversed. If you need this choke, I am sure that they will also produce this one for you.

    Therefore, if you need any Kashke parts, I can highly recommend you PMEC as this company is specialized on these components and the support I received was impressive!

    As for the 2 X2, these are the partnumbers. PME27MD6220KR30 and PME271MB6100MR30. I ordered them through farnell:

    Attached, you can see the new parts – including the 049.769 one with the isolated pins (yellow isolation).

    Hi,

    can someone give me ordering partnumbers for the 2 rifa x2 Capacitors and the 2 red Kaschke coils ?

    my Beolab 3 started to smell burned.  The 220nF X2 is fully blown and has also damaged the 2 Kaschke coils. I already removed them from the pcb but I cannot identify much. In order tobe on safe side, I also would like to replace the 100nF X2.

    is there any further recommendations to replace other parts in order to be on the safe side when the x2 blows up ?

    million thanks in advance!
