Beomaster 7000 bridge rectifier
in Imported Content (Unmapped) · Mar 28, 2019 20:06Finally 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

in Imported Content (Unmapped) · Mar 12, 2019 17:39That's identical too, thanks for pointing it out though. Order is on it's way.
Beomaster 7000 bridge rectifier
in Imported Content (Unmapped) · Mar 11, 2019 17:06Alright. 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
in Imported Content (Unmapped) · Mar 10, 2019 21:22Hi, 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 shor…
Interested in controlling your ML setup with a Raspberry Pi?
in General Discussion & Questions · Jun 23, 2015 10:16I'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…
Audiolink/Powerlink protocol
in General Discussion & Questions · Dec 19, 2014 22:12Hi 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 …
Beolab Penta 6603 MK1 restoration project
in Imported Content (Unmapped) · Oct 10, 2014 21:44[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 diffi…
BG CD 5500 fusible resistors
in Imported Content (Unmapped) · Oct 8, 2014 18:52[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 …
BG CD 5500 fusible resistors
in Imported Content (Unmapped) · Oct 8, 2014 17:55Yes, 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
in Imported Content (Unmapped) · Oct 8, 2014 17:37Hi 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 the…
Amplifiers Beolab 3000 and Beolab 5000
in General Discussion & Questions · Sept 17, 2014 18:07[quote user="tournedos"] OK, in that case it would be rather easy to restore it to the 5000 incarnation as you don't even need to source a missing resistor. I suspect they all would be like that, as it easier in mass pro…
Amplifiers Beolab 3000 and Beolab 5000
in General Discussion & Questions · Sept 17, 2014 14:26In my BL3000 amps the resistor is a regular axial resistor that is soldered in and then one leg is cut off. Don't know if this is the case for all amps, though.. / Johan
Sloppy solder technique destroys new capacitors
in Imported Content (Unmapped) · Sept 10, 2014 10:06[quote user="Menahem Yachad"] This is a PWM, but the actual circuit voltage is only 12.7V. You can see that this cap is rated @ 63V. So, this cap should have been just relaxing. [/quote] Forgive my ignorance but isn't ri…
Beogram cd5500 DAC
in General Discussion & Questions · Sept 9, 2014 10:12[quote user="Leosgonewild"] Johan, open the right-clik the picture and open in a new tab. Then you see the original. [/quote] Duh! Cheers! 🙂 [quote user="Leosgonewild"] Mine is the TDA1541A. [/quote] Mine too. Never see…
Beogram cd5500 DAC
in General Discussion & Questions · Sept 9, 2014 09:49[quote user="Leosgonewild"] I´m guessing that is what he was talking about. Has anyone ever seen this mythical creature? [/quote] Your picture appears to have been cropped. Here Peter talks about the dacs in these player…
Sudden info loss on both Pentas - Beomaster 7000 fault?
in General Discussion & Questions · Jun 18, 2014 12:53[quote user="DMacri"]I could only guess, but I think you're right. The problem sounds like its in the BM, since both speakers are affected. [/quote] Well I wouldn't be so quick ruling out that the fault is in one of the …
Penta I amps, two different problems, orange lights of doom
in Imported Content (Unmapped) · May 11, 2014 16:37[quote user="cordobaman"] Are you including the output transistors in your statement? [/quote] Yes, that's likely. / Johan
Beomaster 1900 paired with S45 sounding terrible, help?
in General Discussion & Questions · Apr 1, 2014 08:22Agree with Søren. These are very old by now. They are probably in dire need of service. / Johan

Beolab Penta 2 type 6622 power issue
in Imported Content (Unmapped) · Mar 25, 2014 16:09[quote user="pepps"] Just doing a little research to find out how to do just that. I presume the crossover is behind the mid-range drivers... [/quote] No, in the bottom. You need to open it where the binding posts are. T…
