  • Re: Correct fuse value for BG 4000?

    Hi Jeff, Good job so far. The 200 ohms reading is a bit strange. Does your multimeter have a range for testing diodes/semiconductors ? Usually marked with the schematic symbol for a diode (arrowhead with a line in front of it). If it does, the readings would be clearer and we will need readings of both ways (pos/neg and vice versa). Alternatively, a

    Welcome to Beoworld ! We've had the arm lift problem countless times here, it's a matter of lubrication and a simple fix. Needless to say you shouldn't use your Beogram before this issue has been solved. Do a search or two and I'm sure you'll find exactly what you are looking for. Martin

  • Re: Beogram 3400 spins too slowly

    Welcome to Beoworld ! Your Beogram is in need of cleaning and lubrication of the motor bearings. It seems to spin freely - just not freely enough. It's a one-phase AC motor so it has almost no initial torque. The bearings are porous bronze, the old oil has hardened inside the pores and will need to be cleaned out and fresh oil pressed in.

  • Re: Silver paint?

    The thin metal plates are stainless steel, not alu. I have tried different things, abrasives, chemicals etc. but haven't found a good solution yet other than replacing the affected panels. Anthony mixed grey-ish paint with some silver and was happy with the result though it obviously didn't have the hairline pattern like the original surface

  • Re: Correct fuse value for BG 4000?

    Jeff, There's not a kit ready for this but I will be happy to help you to the correct components etc. but please put an ohmmeter across the transistors first so we get the diagnose confirmed. Of interest is TR26-33 (incl.), let us know if one or more of them has very low resistance. Martin

  • Re: CD4500 Ringing Sound

    The scope will help you, I think. Check for clean power supply voltages, muting circuits etc. Martin

  • Re: Help needed [:$] BeoGram CD 50

    Could also be the muting circuit goofing up, letting everything read by the laser through. I've seen many cases of cracked solders here. It's on the left side of the bottom PCB somewhere near the power supply voltage regulators. Replace the caps while in there, they can also cause strange faults. Finally, it can be a broken ribbon cable. I haven't

    Wouldn't miss it ! Personally, I wouldn't mind winning those nice and rare B&O candlesticks, definitely collectors items.... http://www.beoworld.org/prize_draw.asp Martin

  • Re: RX2 arm mechanism

    Are you sure that the problem is not with the cartridge ? Sadly, it's quite common to see the needle cantilever suspension give up the ghost and often the symptoms are that the cartridge is riding a little high on the record grooves with the cantilever in an odd angle, producing distortion and often jumping tracks. Give it a gentle finger-dab on
