  • Beomaster 1400 (Typ 2104)

    The question of how to repair the inertia tuning gearbox on these nice old sets (from 1969) has come up a couple of times over the last decade as the original gear sets will have disintegrated. Suggested repair methods have involved rubber washers and bits salvaged from old VCRs. There is a simple solution for anyone wishing to restore the heavy feel to the dial cord mechanism. You will need two 0,5 mod gears, one of 20 teeth, and the other of 45 teeth. RS Components (in the UK) do them and the part

    I tried this on a drill press with not such a great result. Too much run out on my Chinese drill spindle, I guess. It might be fine if you have a Meddings or Fobco or similar quality kit. I don't have a lathe either so I put a call out on a model engineering forum and was swamped with offers of help from good people who wouldn't even accept a bottle of wine for their trouble. You need to remove the flywheel and assemble from the back. Both gears press on.

    Getting the dial cord on was a bit of a faff. The manual calls for a string length of 160cm to be wound round the capstan and the various pulleys and magically knotted by fingers more nimble than mine with the knot in precisely the right place. Or you could pre-tie the knot but then it feels too tight to slip over the rim of the capstan. The vintage radio forums are full of arcane information on dial cord knots, if that is your thing. The solution I adopted was to use a spring to tension the cord

    Gents, Hence my suggestion of an entry level CNC router such as this for GBP 120: https://www.ebay.co.uk/itm/CNC3018-PRO-DIY-CNC-Router-Kit-Engraving-Machine-GRBL-Control-3-Axis-PVC-TK-V2T8/233364263982?hash=item365598142e:m:mm8xH5-0BRW13FGs6v6dXxQ The original cursors were injection moulded as Martin says, but 3mm cast acrylic sheet (the only suitable type for milling) can be bought for a few quid on that auction site and makes a presentable, non yellowing alternative with better clarity.

    Thanks, all. The stereo lamp is on but only dimly. Lamp values are all correct. I will check out what's going on round Tr 15 and TR16 which is where the stereo indicator is switched.

  • Beomaster 1200

    Hello all, Just finishing off a BM 1200. It needed a recap and replacement of some presets, lamps and a broken volume poti. I spent some time making a new cursor out of 3.5mm acrylic sheet by hand. Filing the slim flanges at either end was tedious work and I'm looking at CNC machining sliders out cast acrylic sheet in the future as the price of DIY CNC machines has fallen rapidly. Has anyone had a go at this? The cast aluminium sliders and tuning slide came up well with etch primer and aluminium

  • Re: Beovox S120

    After four applications of Danish Oil with the final one applied with an ultra fine abrasive pad, I have a satin finish that shows the veneer matched cabinets well. The sound of these is utterly different to my more coloured S55 Beovox. The S120s are transparent, accurate and more present for a given volume setting. Bass is certainly not absent. I notice a very slight tendency to shrillness. Recorded piano sound is always a good test, and these pass. The spoken voice is another good test, and I'm

    The S120 is a bass reflex speaker and the reflex port is at the bottom of the cabinet shown here. I thought conventional wisdom has it that the enclosure shouldn't contain too much sound deadening or the reflex function will fail to work. Also, peculiarly, the gasket sealing the resin loudspeaker plate to the cabinet only extends a short way down the sides of the enclosure.
