  1. FM Radio to stay

    The Daily Mail reports the BBC has cancelled plans to switch-off FM radio broadcasts and force millions of listeners to tune into digital transmissions The corporation is set to announce FM will remain as part of a 'hybrid' future that will operate alongside DAB and the internet. 'We all once thought that DAB was the only digital future of radio, but audiences want choice,' BBC Director Bob Shennan will tell a radio industry conference in Vienna. Read the full story at Alan
  2. Power supply build

    Hi The transformer shown is only 12V with a single winding, the OP needs 21V so will need a 36V Transformer. or 18-0-18 according to the PSU kit details. Alan
  3. I feel that with £1K to £2K you may not get what your looking for. A change of speakers may make the most difference and some of the newer ones are more "forward" and "Brighter" in their presentation but can be fatiguing after a while.I have had many speakers around the £800-1200 but I needed to spend £4K to makea significant difference. The same is true of the amp which is functional but somewhat conservative. Perhaps you need to look at the Likes of Rega, Musical Fidelity etc. I see most items on your wish list are 4 to 5 £K each so even 2nd hand you could only change one item. Alan
  4. Power supply build

    Hi, All the parts you need are on the link you provided , I was going to list my suggestions however unless you have experience of wiring up transformers in series/parallel and mains I feel that I should take a step back due to elf and safety. I see you already had a shock back in August 2016 Please dont take offence but from the questions you ask then and now, I feel you should know the answers already if you were to tackle this project. If you were nearer to me I would be pleased to oversee this project as we all have to start somewhere.(I have been in electronics for some 50 years) Also I dont think it will be any different to the timestep you already have. Alan

    I looked at the regulator page you linked too. It says at the bottom of the page that the transformer should have an output voltage of about 1.5 times the voltage you require, So 20 volt would require 30V. I would like to see something ,more efficient as you would be wasting some energy as heat, but that how they get the regulation. The supplies look nothing special. I would prefer to see more active components in the regulation stage. Dont forget to include some fuses in the final design (Mains & DC o/p as a minimum. The transformer should be rated at 30W or more ,Dont use a 220 Volt transformer from China but a 230/240 V from the likes of RS or Farnell.

    I agree with Kevin and greybeard it would be hard to DIY something better than the timestep.(See photo). You could buy a "laboratory" PSU like this one from HP which is very stable and temperature controlled. I picked one up for £75 second hand. Mine is 0-24V @ 1.2A (not quite the same as in the stock photo) but I dont use it with turntable. Alan
  7. Celestion SL700 If I only had any skills

    Do you mean these ? Alan
  8. Is it just me?

    I can remember the DIN standard and a couple of Manufacturers like Philips and Grundig were compliant, but the spec was fairly lame and it did nothing for their future products.Its rather like a "which" review where they will say something like the £4K speakers sounded good, but at the end of the day the £100 speakers offered better value for money, and even if they failed you could buy many more pairs to reach £4K and the sound was not 400 times better. Also think of connectors designed by committee like Din Plugs and Scart Leads !!!! (terrible things) very often a specification is the minimum standard to allow most manufacturers in, rather than a high level to hope manufacturers will aspire too. Here is the spec....... If this had been adopted we would all have BSR Autochangers and speaker which go down to 250Hz +-6DB and amplifiers with distortion not exceeding 1%. Alan
  9. Have you tried the recent prestige or classics series, although not cheap I guess in its day the original drivers were quite expensive new. ?, plus you only needed a single speaker cabinet (mono) whereas now you need a pair for stereo effectively doubling the cost. Alan
  10. Interesting article. There are some differences between the Tannoy and KEF method. As you may know the Tannoy uses a tweeter mounted some way back behind the bass driver, and uses a horn to get the sound through the magnet of the bass driver. In later years KEF were able to use better tweeter magnets and put them right in the centre front of the bass unit without the need for the horn.Over the years slight variations have included Tannoy Tulip and KEF tangerine Wave-guides. I have used both types and agree that they do work quite well as a point source, since with a conventional "tall" floor stander you can hear the the music being split vertically across the drivers, especially if you are sitting too close. I think that the KEF system maybe technically better, but having owned quite a few KEF speakers with Uni-Q drivers I have found reliability to be an issue,perhaps due to the complexity of the design to mass produce a product and dare I say manufacture in china. The Uni-Q tweeters have very little heat-sinking and virtually no protection for the voice coil. I am currently in the Tannoy camp Alan
  11. Is it just me?

    Very few speakers are 20Hz to 20KHz with a ruler flat response. Some may quote + - 6dB. plus many music sources do not need that frequency range. At the present time I am listening in my home office to my clone LS3/5a and I hear good quality music, and I doubt if there is any output below 200Hz and given my age I doubt if I could hear much above 10K. the 20Hz to 20KHZ is more an amplifier specification stating it will allow a range of audio frequencies through without attenuation or undue distortion. So a HiFi speaker need not be 20 to 20K. Alan
