  • Re: Beomaster 7000 bridge rectifier

    Finally I got the part today, it took a long time to deliver. I soldered it in and everything works just fine. Thanks for your help! / Johan

    That's identical too, thanks for pointing it out though. Order is on it's way.

    Alright. It seems to be a few millimeters smaller and the pins have the exact same footprint from my measurements. I guess it's a winner then. :-) Thank you both! / Johan

  • Beomaster 7000 bridge rectifier

    Hi, my trusty BM7000 decided to die on me the other day. Today I got around to taking the lid off and do some trouble shooting. It turned out the F1 fuse was blown and after some measuring the D3 bridge rectifier is shorted. I haven't been able to find anything else that seems broken so I'm hoping that replacing the rectifier will bring it back to life. Now, my question is what to replace it with? I was browsing some component sites and found this one: https://www.elfa.se/sv/likriktarbrygga

    I've been meaning to do this myself sometime in the future, but if you're doing it and I can buy it, then sign me up! :-) Like Mika I want 2 if the price isn't too high. And I'd prefer soldering connectors myself if that keeps the price down. Very cool, keep it up! Cheers / Johan

  • Re: Audiolink/Powerlink protocol

    Hi Gert, the file is available somewhere but I don't remember where. The question, though, is how you want to connect to the unit (and what unit it is)? Is it through the 7-pin connectors or the speaker sockets? It will make a world of difference. And the file only gives some hints (not much at all) about the speaker socket connection. Either way it shouldn't be too difficult if you're stubborn. / Johan

  • Re: Beolab Penta 6603 MK1 restoration project

    [quote user="StuckE30"] OK so please correct me if I'm wrong but TR25-27 (SC3281) and TR30-32 (SA1302) are the output transistors? Initial investigation looks like both of those transistors are NLA from Toshiba and difficult to source unless you want the cheap Chinese knockoffs. (I don't) [/quote] They are discontinued but have been replaced by new versions (and new numbers). I can dig out what they are if necessary, but you should be able to google it. The new ones are readily

  • Re: BG CD 5500 fusible resistors

    [quote user="chartz"] I replaced those with ordinary fast fuses on holders. There's enough room to do that, and It's been 3 years. The cause for their melting was two bad caps (shorted) in the PSU section. The zener was gone too. [/quote] Ok, sounds sane. What rating? To be honest I haven't done more trouble shooting than finding the faulty resistors yet. But everything seems to be working normally apart from those, so I think it was me rather than a bad cap. I'm not aiming

  • Re: BG CD 5500 fusible resistors

    Yes, I suppose. I just figured there was a current figure to take into account, but perhaps that would have been in the manual then? Forgive my newbieness, I've never had to deal with these before. Thanks! / Johan

  • BG CD 5500 fusible resistors

    Hi everyone! I've been trouble shooting my old CD 5500 that did nothing when plugged in. I traced it down to R11 and R12, one measures in the MOhms and the other is open. As I can't find a fuse I can only assume that their purpose is to act as such. My question is what to replace them with to get the same behavior in over current situations, i.e. to work like intended? Now, before you come suggesting there's a reason that they blew and I should find out why (rightly so!), I did actually
