  • Re: Off - Topic: Durban/St. Lucia area of South Africa

    Happy memories - as a kid in the 60's we used to go there for our December holidays. Great beaches - including the sharks - I remember the shark nets, and once in a while the locals would pull a captured shark onto the beach. Now THAT was fun! One day, when I win the Lotto, I want to go back there for a long holiday again - Margate, Scottburgh and

  • Re: BeoCenter 9500 problem

    I've got a nice pile of scrap CDM2 lasers, which I thought I could warehouse for when needed in BG5500's, BC8500's, BC9500's etc. No luck. There are more dead scrap lasers than good scrap lasers out there. Unfortunately. Tread carefully before parting with your hard-earned cash on used CDM2's - there's no guarantee that the lasers

    This is the Tonearm PCB after redoing the wiring correctly. If your's looks like this, you're OK.

    This is the Tonearm PCB, with the +ve and -ve signal leads reverse-wired. Don't all rush now, but if your's looks like this, you've got some very patient work ahead of you. And if it turns out that more of you have this (I hope not), then there was a production defect.

    [quote user="Step1"] I would say the white led's give out far more forward light than the orginal underdriven incandescents did and if not carefully done this could cause problems in the 4000 more than the later models due to both photocells recieving light... [/quote] And that's exactly why I buff the LED's with sandpaper, to

    Soren, yes, it works, but you have to use a bright LED. As I mentioned before, between 15,000 - 50,000 mcd works well. The next stages are now done. As most of you know, I am not averse to using newer technology, especially where it can enhance the performance of the unit, but does not detract from either its reliability or "originalness"

    Here is a picture of 4 of my LP's - encircled in color. The top 2 are CD4 - RCA Quadradisc, Project3 QD The bottom 2 are SQ - Project3 SQ and SD Those are the most common markings. JVC used "CD" (ha-ha - a sign of things to come) or "CD4".

    One of my dream units - a BeoGram 4000, rescued from the skip. First time ever I've had one of these. Really bad condition, non-working, cracked cover, etc - the writeup is in the Workbench forum - Beogram 4000 Restoration Menahem

    You can use the CD4 Din5 input at the rear for any line-level source - I use mine for a CD. That leaves the Tape inputs for Tape and VCR - you can play with the front and rear inputs, and the Stereo button to get whatever you want on all 4 speakers, or 2 at a time. Over the last 10 years, I have restored 3 BG6000 quads, but each time I demonstrated

    I now have all functions on the keyboard. I removed all the brass fittings, cleaned with contact cleaner, straightened the flappers, and resoldered everything. The epoxy balls on the plungers worked just fine. LED done - works perfectly. Got rid of that ugly 100ohm poti. Made a new box to hold the LED, from a yellow plastic biro pen stem. See the pic
