[quote user="expoman"]Mr. Torres is with Nokia.[/quote] Not since about a year or so. He was one of the folks that took up & left after the Meego platfrom collaboration with Intel was axed. 6,200 shares isn't that huge a commitment for anyone in an executive position - it's worth about 54,000 euros at current prices. Besides, they

[quote user="HarryPierce"]or am I on the wrong track about the meaning of 'carrier frequency'.[/quote] I'm afraid you are - as I said, the wavelength of the IR led isn't too critical here. Any IR led will do. The thing is that the command codes you see described in the service manual are low frequency (as you calculated) pulse

Are you really after the wavelength, as opposed to the carrier frequency the transmitters are driven with? The wavelength usually doesn't matter - although it can vary on the data sheets, the receiver components have quite wide response curves and generally all IR photodiodes / transistors will be sensitive to the light from any IR LED. The carrier

The service manual on site says the crossover points are 120/600/2000 Hz.

You may be referring to Innovus RAone SmartDimmers - the company web site has disappeared, so I'm not sure if they are around at all any more. I bought a bunch of these a couple of years ago when they were on sale. Basically they work fine, but there are a couple of drawbacks: Most of them make a high pitch noise, some units more than others, which

It is so pretty, I had never seen any of the 4500 components in person before and I'm quite tempted to start collecting a set - but for now, the Beocord will go back to the safety of its comfy box, I'm not going to be the one to make the first scratch... Thank you, Lee & Beoworld - and anybody still thinking about becoming a gold member

I interrupt Stevie's silky smooth Tin Pan Alley guitar mastery and exercise the functions. Some operations are slightly erratic, so I believe I need to treat the Beocord with one of Dillen's belt kits - not too surprising after 20 years in storage! Oh dear, I think I made a fingerprint

Four months into the move, I had conveniently carried my cassettes up to the new flat already last week. So the DIN cord goes into A.TAPE2, the power plug into a free socket, the lid opens smoothly and quietly when I touch LOAD, a Stevie Ray Vaughan recording from 1986 goes in... and it plays!

Need to put it somewhere at least temporarily, and it doesn't look that out of place on the BS6500 stack...

What do you know, it is an absolutely spotless Beocord 4500!
