  • Re: Beogram 6000 CD-4 Distortion

    The cable itself is CAT5E, but the Connector is an original Hirschmann 5-pin DIN. The turntable is connected to the BM3400 Phono-4 channel input, as it should be. This input is, in effect, a line-input. It is a beautiful unit, and much enjoyment was had in restoring it. Is there anyone out there who has an MMC20EN with a BG6000 or BG3400, with a real

  • Beogram 6000 CD-4 Distortion

    Hi all, I have just finished restoring my new (old) BG6000 CD4 with MMC20EN. I bought it off Ebay about a month ago, cosmetics were pretty near perfect, but it was butchered inside: The cable to amp had been replaced by a home job with 2 RCA plugs (wired directly to the original 9-pin plug on the CD4 Demodulator board; Non-original screws and bolts;

    Andy, you are too kind! Yes, it is a great feeling of satisfaction. I love doing these electronic things myself - ever since my fantastic dad bought me a Radionic set (I still have it) for my 10th birthday!!! When you get to your Beocord 1700, give me a call - I've got some left-over bits for that. Actually Martin Dillen gave me a lot of help in

    And now to close up the cabinet, and connect them to the BC9300 receiver. The BC9300 specifies 2 x 80W into 6 Ohms. The S45's are 45W, 4 Ohms each. So I've got the wiring hooked up with each amplifier channel feeding 2 S45's in series, total 8 Ohms (nominal) impedance per channel. That's AOK in my book. Over to my favorite music LP's

    Hi Simon, The slots are a crude attempt at a cheap through-the-hole bread-board. Holding the board vertically in one hand, the insulated part of a wire in the other hand, and the exposed portion in your teeth, you pull the exposed portion downwards through the slot! Right! You get the idea! Then you twist together the exposed portions of the other wires

    Hi Andy, Thanks for the comments - kind of feels like "Big brother's watching you!" Back to the project: Auricap sent me 12 x 16uF 400V, even though I had ordered 15uF. Not a big deal, as they measured out at between 15.7uF to 15.9uF each, and they are spec'd at 10% tolerance, so that's just fine by me. The 400V spec is super

    Hi Francois, I've had a lot of luck with Solen Audio Metallized Propylene Audio Capacitors (made in France) - quite inexpensive, and high quality - try www.solen.ca The PB680 6.8uF 400V is $3.35 FOB Montreal. I decided to use AuriCaps on my own speakers - much more expensive (retail - about $48 each for the 16uF model), but through contacts, I got

    Here's a close-up of an "alert area", which jumped right out as very obvious. 2 of the 3 capacitors are showing that they are joined together. Nowhere in the circuit diagram, are 2 capacitors shown joined together. After examining the actual board wiring, I deduced that the positions of R5 and C3 were reversed. I have seen many instances

    This is the XOver still mounted in the cabinet - it has 2 screws to remove it. The board is made from paper fibre, with wiring slots on one side - really cheap stuff, but it's held out for 30 years.

    That's the nice part about this site - there are many good things from one another's experience to enjoy! Here is the circuit diagram, which I wanted to compare to the actual wiring onboard.
