  • Re: Third NEW issue with Beogram 4002

    Hi Jeff, My BG6000 is also an ex-Canadian unit, which apparently had many unauthorized fingers fiddle with it over the years. Slowly, I've been taking care of all the previous sloppy workmanship, as problems came to light. My latest problem has similar symptoms to yours, which I've traced down to the PhotoResistor circuit. See this post: http

  • BeoGram 4002 / 6000 PhotoResistor

    Hi all, The PhotoResistor on my BG6000 is not operating correctly. I opened up the assembly, and the installed component appears to be a non-original Motorola substitute part (appears to be 2N5779 PhotoDarlington), as it has 3 leads, but only the Collector and Emitter are being used, and the Base has been cut off. Cutting off leads is definitely not

  • Re: beomaster 2000 tuner string replacement

    Hi Gregor I have the Beomaster 3400, which has the same chassis as your Beomaster 2000. I'm not sure if it has the same dial-cord arrangement, but here is a picture of my unit - perhaps it can help. Also, I have since restrung the cord with fishing-line. Very strong and durable.

    If you disconnected the power PCB, you need to start at the beginning, and check the circuit after the fuses. You may have an intermittent short, hidden under the transformer or in the rectifier area. Check the connections around the large Power Supply caps, and the transistor next to the motor.

    OK, You said it was working great. Then it wasn't. After it was working great and stable for a while, did you open it up, and change/adjust/fix anything? Even something small? Sometimes something which seems insignificant, sets off a chain of events which results in a failure. It's highly unlikely that you blew the transformer - these things

    Hi Argee On your other posting, you mention that the BG4002 works great. Here you say you've got a problem. Is the problem solved, or have you got 2 BG4002's? Menahem

  • Beogram 4002 / 6000 Problems and Solutions

    Hi all, After many trials and tribulations, I have completed a total overhaul of my BG6000 Quad, which I bought last year on Ebay from a used HiFi dealer in Toronto. Previously, I thought I that had fixed all the problems, but as I progressed, hidden defects came to light, which the previous owner/technician had intentionally hidden quite skilfully

  • Re: Beogram 6000 / 4002 33/45 LED Indicator Upgrade

    The last problem (I hope) I had to deal with, was the 33 and 45 indicator lamps heating up, and burning/deforming their plastic housings. I am a fan of LED's, primarily because of their long-life, cool operation, and highly-directional intensity, even though the associated resistor warms up while killing excess voltage. And I also know that some

    Then, I got challenged again with this problem, which Mika in Finland helped me, by solving the problem before I had to deal with it. http://forum.beoworld.org/forums/thread/87400.aspx Beogram 6000 prematurely ends play ________________________ Mika wrote: A final observation, which I'll post in case it might help someone searching the forums for

  • Re: Beogram 6000 / 4002 CD4 PCB Capacitor replacement

    Now that I had the machine working physically, I naturally wanted to listen to some LP's. So I put on one of my CD4 Quad LP's, and ended up with this problem: http://forum.beoworld.org/forums/thread/66387.aspx Beogram 6000 Muddiness with CD-4 Basically, I replaced all the Electrolytic and Tantalum Caps with a nice blend of Elna Silmic II, and
