Trio Kenwood KD-1033 turntable main bearing service

  One of my first posts in this blog was regarding the servicing of the Pioneer PL12D turntable, and that has proven to be the most popular by a significant margin. The Pioneer PL12D had its competitors, and probably the most popular alternative was the Trio Kenwood KD-1033 turntable. I use both names (Trio and Kenwood) as the company operated under different names in different markets. In the UK they were Trio, possibly because the brand Kenwood was most famous here for food blenders. 95% of a KD-1033 is similar to  Pioneer PL12D, and servicing them is very much the same process. Both are belt drive , have an AC synchronous motor,  mechanical speed change , a main bearing, sprung top deck and rubber motor mounts. the KD-1033 uses a different type of anti skate mechanism, employing a thread and weight. The plinth is shallower with an internal cross brace. One aspect that is different is the design of the main bearing, and servicing it is a little harder than a PL12D. The ...

LED light bulbs are now good enough

A number of my posts here regard my battle to replace GU10 and MR16 Halolgen bulbs with LED equivalents, via a short period of CFL bulbs. This has been successful, with all the 40 halogens having been replaced with LED some 5 years ago. My energy consumption has gone down and so has the amount of heat generated into the loft and ceiling space from the bulbs. Since then I have kept an eye on LED full size light bulbs for ES (Edison Screw) SES (Small Edison Screw and Bayonet fitting bulbs, all of which are represented in my house. Until recently I had found the LED lightbulbs to have dimmer light and a cold blue tint, much as the first Halogen replacements had. A few weeks back while in my local B&Q DIY store I saw a display of Philips LED Bulbs, some of which featured clear glass and a kind of internal perspex crown-shaped diffractor. I'm pleased to say I have tied both in SES , ES and Bayonet form-factors and they are superior to the Com...

Reducing your electricity bills

I have been monitoring my electricity consumptions for a number of years on the basis that, in order to reduce it, i need to understand it first, i.e. where does it all go ? Initially I took a reading from the meter once a week , then subtracted the past reading from the current reading to get the weekly usage. I did this in a spreadsheet. Now I use The imeasure which is a web site run by Oxford University. It does this and many more things, including gas consumption and factoring in weather conditions. I also monitor my real  time using a current cost device, monitoring the whole house, plus a couple of individual appliance monitors (IAM) which provide me data about individual appliances. I can publish this data to the Internet via the current cost NetSmart unit. All these methods give me a better idea of what I'm using and where it's going. I should explain that my household uses gas central heating as the primary source of heat and hot water. My weekly electricity usage...

what to do with an old hard drive

Over the years I have accumulated a number of old PC hard drives. Some were mine, other from neighbours & friends who asked if I could "fix their PC". It occurred to me that I had a burden of responsibility for these disks, if someone got hold of them they might be able to extract confidential data. In each case I had determined that the disk was dead or dieing, having failed the manufacturers full surface test (via Ultimate Boot CD - UBCD ), but conceivably the disk could be attached and read on another computer. They might contain personal data - so I decided to put these disks beyond recovery. First you have to dismantle the hard drive. this involves removing all external stickers from the disk , and with a torx driver (purchased from your local hardware shop - in my case the always helpful W. C. Baker of Fleet ), remove all the bolts which hold it together. An excellent video of how to dismantle a similar hard drive is here : Once the disk is in bits th...
