  • Beolab Penta 1(6602)

    I've rebuilt these super speaker's,and although there are now more teeth marks along the edge of the workbench,I'm pleased with the result. I'm puzzled though by the action of the standby light. I remember that this glowed dimly red in standby,then went green as the unit powered up.If the light turned yellow at any time(fault mode!)you reached for fire extinguisher and paracetomol? On both of my units,the light seems to be orange in standby,then brighter orange at power up.No yellow

  • Re: Beocenter 9500 smell...

    I allway's assumed that the "beopong"was due to the material that was used in the pcb's? Later and current product uses glass fibre in the pcb's,but this just seems to emit a different albeit lesser smell. The B&O policy of their systems being in standby continuously means that some components are getting warm and giving off scent too of course. With the hysteria over energy conservation of course,all equipment nowaday's is very frugal in consumption. Nick

  • Re: Beocord 6500: drawer not moving

    Indeed,but have you established that the data route for that function is continuous,as suggested above? The fact that you can't operate play,wind and rewind either,suggest's that the data route for those functions and "open", is missing,or perhaps the processor ic is faulty? Nick

  • Re: Beocord 6500: drawer not moving

    Sorry,yes but you will need a compatible Beomaster eg Beomaster 5500/6500,to operate with remote control,as the commands come via there. Another easy check is with a multimeter to check the continuity of the data route. With the Beocord unpowered,and the meter in a low range resistance mode,put one probe on pin 32 of IC9(one of the two processor ic's on main pcb)and the other probe on pin 21 of the same ic.When you click the "open" button,the meter should read about 1k ohm when the

    Are you able to "get technical"?Do you have a logic probe or oscilloscope?It's most significant that the data for all the functions (inc "open") you mentioned is not getting through to the processor? You may have a faulty processor,but it's unusual. You should see activity via a 'scope or logic probe on pins 21,22,23,and 24 when you operate the keyboard.(pin 21 being the crucial route for the functions you mention that don't work of course) Are you able to connect

    Ah,that's significant!!! Those functions all share the same data route from the keyboard to the processor. Check the soldering on the connector P13 on the main pcb. Nick

  • Re: I cannot get sound out of my beocenter 9300

    Yes indeed,it's another of those "what if" type questions! I assume that B&O had foreseen a development that they thought they should prepare their systems for? Equalisers were the big thing for a while,but seemed to be at odd's with the B&O ethos? Hey ho,they have alway's moved in mysterious way's of course,and their current moves continue to baffle? Nick

    Only on the '9300 and '9500(American versions) in fact,None of the European versions had these connections as far as I can tell? We saw them with BM6000 and Beocenter 7700,and of course Beomaster 6500 too.Can only wonder why they were only fitted on some model's? Discuss? Nick

    By the connections being the same,I meant + and -,and the ac input.Some maker's have different arrangements for these. Nick

    What loudspeakers are you using? Is the line in/out dummy plug in place on the connection panel? Nick
