Oh, good job ! And thanks for posting the result. Martin

Hi Jeff, Yes, always ship the platter separate from the Beogram. Wrap the platter in bubblewrap plastic and place it under the Beogram. Dismount the cartridge. Cut a piece of foam to fit under and above the tonearms so that it is slightly squeezed when the lid is closed. This will secure the arms during transport. Close the lid. Wrap the Beogram in

The CD 50 is a Beogram, this means that it accepts Beogram commands. But it's at line level so that will sound terrible when connected to a phono input. This means problems if you haven't got a Beomaster with a dedicated line level input for a Beogram CD (like f.e. the Beomaster 5000 series). I'm afraid that you will have to dismount the

Lift off the platter. Losen the (5 or so) screws that hold the plastic frame and remove it. Then lose, I think, 4 screws holding the turntable chassis. Martin

Thanks for the tip about the dial. I have made a couple of other dials this way. Some even involving laserprinter water-transfers and the results were very good. However, the problem with this particular set is that large parts of the dial lettering is in white and, apart from serigraphic machines, it is practically impossible to print white on clear

It's a construction flaw, causing the electronics to accept twice the frequency of the motor circuit than normal. If the turntable belt is slipping, the motor will accellerate too fast and the electronics haven't got time to correct and happily accepts the double speed. It happens in Beogram 2200,2202,2400,2402 too and I seem to remember that

The majority of the original leads used in this radio is of the type with rubber insulation. This type of insulation is known to become brittle and crack over the years, leaving the wires inside bare to short to eachother or whatever comes around. Even leads with fine looking insulation will often crumble to pieces when touched. Looking at the chassis

The volume potentiometer is missing alright. Only the metal tube used for the push/pull mains switch and the mains switch itself is present, the latter being well past its best days in that it's completely frozen. At least one ceramic capacitor sits with one lead flying in open space, presumably in need of a tag on a volume potentiometer to connect

Jeff, We've had this up a couple of times. The Beomaster 2400 and 4500 are two very different machines. The 2400 has a discrete DC coupled amplifier that will accept a lot, though without any safety circuits to avoid distortion etc. whereas the 4500 has an integrated hybrid IC, one chip that holds both channels with some safety circuits. The 4500

Disse decks har aldrig været specielt gode til at spole, særligt fremadspoling kan være svær at få til at køre godt selv med nye dele og selvfølgelig værst mod slutningen af båndet, så forvent ikke mirakler af den. Tilbagespoling kan man som regel godt få til at virke OK. Koblingen
