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 ...

CurrentCost IAM device

Inspired by the success of my bridged energy monitor which enables me to publish to and access data from the web, I decided to also get an IAM. CurrentCost is a household energy monitor, which uses wireless technology to communicate with an inductive 'clamp' installed around the mains electricity cable in my meter box (see other currentCost post).

Recently the bridge enables the display to post data to the web. The IAM is a small unit resembling an electrical plug with a socket on the back. Basically you unplug a piece of equipment in your house, plug it into the IAM and plug the IAM into the wall socket. What it does is enable you to monitor individual appliances in your household using the CurrentCost display, in addition to the whole household. My Display supports up to 9 IAMs in addition to the primary function of displaying the total household consumption.

I've always been a bit mystified as to why my background usage never falls much below 300 watts. Even while on holiday, the house would routinely be using 400-500 watts. No lights or TV were left on , nor heating. I thought the IAM might give me some insight into different appliances behaviour i.e fridge/freezers.

NOTE : Currently the Bridge cannot export IAM data to the web but this is being addressed by the new bridge Mk II renamed netsmart.

Hi, did you work out what the 400-500 watts were being used by?

Thanks KCA, yes. In the end I was surprised by how much energy went on refrigeration. The background use was a fridge freezer, a fridge and a freezer. The latter is one of those American style units, and not the most efficient. Turns out I'm using around 4 units per day on just refriigeration, which was a surprise. Replacing old or inefficient fridges and freezers could actually have a greater impact on my household consumption than say, lighting or standby devices

Restoring a Pioneer PL-12D Turntable

 I got back into vinyl records about 18 months ago, and have collected a few hundred albums, mostly second hand. I have a number of turntables (NAD 5120, Ariston QDeck, Pioneer PL12D ) which I got also second hand. I keep a few, some end up passed onto friends, some that are too far gone are kept for spares. In most cases they have required a little work to get them running again. Last week I was lucky enough to get a Pioneer PL-12D turntable from freecycle. The lady who offered it, said that she in turn had received it from freecycle , and had replaced the belt but couldn't get on with the springiness of it, and had got a modern USB turntable. I have previously worked on one of these decks, and know what she means about the suspension system used. While this blog is specifically about this particular model of deck, many of the concepts are similar to others from this vintage. Many Japanese belt drive decks throughout the  1970's shared very similar construction, so this m...

Replacing MR16 Halogen bulbs with LED equivalents

If you have read my other blogs about GU10 mains voltage halogen lighting, you will know that I have mostly replaced these bulbs with LED equivalents. they cost more, but last longer, are cooler and use a fraction of the energy. a halogen bulb is typically either 35 or 50 watts. most LED bulbs are 3 watts. While the bulbs in my house are predominantly GU10 mains halogens, I do have a couple of MR16 bulbs. These are a different type of halogen that operate from a 12volt supply. I should mention at this point that I don't have any dimmer switches in my house. Now some mains voltage GU10 LED bulbs are dimable (always check first). MR16 bulbs have two pin connectors rather than the lugs found on GU10 bulbs. GU10's use a push and twist method of connecting to the socket. the MR16 simply push in place with metal clips also gripping the edge of the bin base. They use a separate power supply , either a transformer (old type ) or a switch mode power supply(newer) to convert 250v ...

Mending a pair of M-AUDIO BX5a monitors

One of my sons friends asked me if I could take a look at his speakers which had stopped working. he and my son had been mixing some songs using a pair of M-AUDIO BX5a monitors. These are bi-amped active speakers, with Pro audio style inputs (XLR and 1/4" mono jack). They each have two integral amplifiers so only need a line or balanced input. Each speaker also has a mains power input and a volume control, and a blue LED on the front to indicate power. The speakers have two drivers, a small domed tweeter and a small 5" Kevlar woofer. One had developed a loud buzz, coupled with a very loud 'thump' sound when powered off. The other had completely lost all bass output.The speakers were only 13 months old, which seemed a very short life for a pair of speakers - I have speakers made in the 60's that are still going strong. However with additional electronics in these BX5a's I'm not really comparing like with like.These speakers are self contained audio system...
