If you look back at an early 1960s catalogue I have they are actually shown as the speakers of choice for the Beomaster 900K to enhance the stereo separation! Brian

Whilst the frequencies were unique to B&O equipment (ie the Beolink 1000 etc will not drive it) I did buy a Memorex universal remote (over 20 years ago now - I have just thrown out the spare keypad covers for it!) that worked a BM 5000 / VHS91 set up with a small colour portable TV. The snag with the Memorex remote was the batteries would go flat

You might want to edit the title to read MCP - Master Control Panel.... Most people who read it will be able to identify what you are after - but not a search engine! Brian

Turn the panel towards you until its controls are resting on some soft material - (a cloth spread on your knees is not too bad for this!). The battery panel should then be on the left hand side. It slides towards the foot - use a thumb nail to gain some extra purchase and slide to the left (assuming you have the two feet at the front nearest you). The

You can check how many hours of viewing it has had - that should be a better guide to tube life rather than simply the age. Otherwise I suspect it is a question of finding a good used one.... Brian

Does anyone know where I can obtain a suitable cord to replace the tuning string on a Beolit 500 from the 1970s (coloured panel models rather than the earlier wooden table radio) ? Sadly after almost 40 years it has snapped! Brian

Personal opinion - but if you want another to help bias you before you decide, I would go for the 4000s. Brian

If only all problems could be solved so easily! Once again it shows the value of an excellent forum (so thanks to the founders) and the valuable help offerered. Brian

Yes - but you might want a pair of Beovox Pentas (without amplifier) rather than the Beolab ones! Brian

Personally I do not buy into the argument that you need 150 watts to drive a 150watt speaker! The ratings on the speakers are input levels and a bit like 0-60 times for a car - pretty meaningless if one car is geared for the next gear change at 59mph and another at 62mph! Check the sensitivity (or power at a consistent level of dB) in the specifications
