Beogram 8000 hum and crossover
Hello,
I have just bought an old Beogram 8000 with a nice MMC20CL pickup for the amount of Danish money that is equal to 40 pounds . I have just sent my BG 4002 to repair because of a speed probem. I hooked the 8000 up with a "Tape 1" cable with datalink from my dad's beocord 8004, this is of course inducing some hum, but i get a "cykling" hum when the pickup is on a record. It is like it is humming when it has spinned one turn. The Datalink is not responding on the BG, but the "beep" signal is reaching to the speakers, as if the datalink signal is being amplified. I know that double screened cable is required for proper sound, but this thing is humming rather loud, like it is not being grounded at all. Is there anything I can do for bringing this old beauty back to life? It is only temporary, as my BG 4002 is sent to repair (at a former B&O Tech), and is taking some time, as he no longer is doing it for a living....

Re: Beogram 8000 hum and crossover
Jeg har lige købt en billig Beogram 8000 med MMC20CL pickup. Der fulgte ikke noget Dobbelt skærmet kabel med, så jeg bruger min fars Tape 1 kabel fra en Beocord 8004.
Datalink fungerer ikke, selvom at det brugte kabel har fuld gennemgang i alle ben. Istedet kommer Datalink bib lyd istedet. Når der skruet op på normalt lytteniveau (for mig rimeligt højt) er der en slags brum som kommer efter at pladen har kørt én omgang. Det er lidt svært at forklare... Oveni støjer den sindsygt meget som hvis den slet ikke er jordet. Er der en billig midlertidig løsning, da min primære pladespiller, en Beogram 4002 har et problem med at holde hastigheden, er blevet sendt ind til en tidligere B&O rep.

Re: Beogram 8000 hum and crossover
Mønsteret på tachoskiven under pladetallerkenen er faldet fra hinanden, så hastigheden aflæses forkert for hver omgang. Jeg har nye repro skiver i rustfri stål.

Re: Beogram 8000 hum and crossover
Hvad kommer sådan en skive til at koste?

Re: Beogram 8000 hum and crossover
Er tacoskiven et rundt stykke metal med riller med en diameter på ca. 8 cm, som sidder ved lejet?

Re: Beogram 8000 hum and crossover
Ja, det er den. Den er fremstillet med en fuldstændig sindssyg præcision. Hvis den er i metal i din Beogram (ikke fotografisk fremstillet) og ikke fysisk beskadiget, er den ikke skyld i fejlen. Hvis den er fotografisk fremstillet, er den sandsynligvis årsagen. Du har en besked i din inbox (øverst til højre).

Re: Beogram 8000 hum and crossover
Har set beskeden, men kan en skive fra en Beogram 8002 sættes på istedet? Min far har nemlig en "Donor" til hans egen 8002, men hvor mange dele er identiske med BG 8000, hvis det er?

Re: Beogram 8000 hum and crossover
Skiven passer fra en 8002 (som noget af det eneste) men man hugger da ikke bare en tangential pladespiller af denne karat op for dét, slet ikke en 8002 !

Re: Beogram 8000 hum and crossover
Brummen kommer fordi kablet er helt forkert afskærmet til en pladespiller. Tape og Phono kabler er ikke lavet på samme måde. Du skal bruge det rigtige kabel.
