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 Pioneer main b

Current Cost CC128


My latest gadget, which I have had for a few months is the Current Cost CC128. This device displays how much electricity we use , in real time. It also gathers historical data which I can download to a computer for analysis. There are quite a number of these type of devices from Owl, Wattson and others and they all work in broadly the same manner.


The device has a display unit , as seen in the picture. It communicates with a sensor which you install alongside your electricity meter via a wireless connection.

The sensor unit has a clamp which loosely attaches around the cable leaving your electricity meter. That's it ! Takes about 2 minutes to install and does not require an electrician. Nor does it interfere with your electrical supply or wiring in any way. Completely non invasive.
I had previously had an Owl device which worked very well, but did not record historical data. I passed this unit on to my mother-in-law who is using it in France, where it also works well. I chose the CC128 for a number of reasons :

  • It keeps historical data
  • There are a number of open source projects to provide integration between the unit and a PC/Mac for charting and analysis. Dale Lane has written a very nice application to allow you to download the data via a USB cable to your PC. Dale is incredibly knowledgeable on this subject , extremely helpful and his application is free, so I salute him.
  • CurrentCost hope to bring out additional sensors in the future, possibly including gas, oil and water consumption too. These would have to use a different approach. The electrical sensor uses induction to measure consumption. With gas the sensor would have to be an optical sensor which 'counted' the rotations of the smallest units on the meter.


I'm trying to reduce my energy consumption, which I consider to be far too high - approximately 21 units per day, and I'd like to reduce it . The CC128 helps me in a number of ways. I have the display setup on the window ledge by my kitchen sink. I can see at a glance what the consumption is . It's sensitive enough for me to be able to tell if unnecessary devices are on, for example lights left on upstairs. I can see the data presented in various forms, including KwH, KG CO2 or Cost in £/€/$. It also gives me a handy graph of the previous 24 hour period, in terms of Night, Day and Evening use.

Now of course I could gather some understanding simply by recording data from my own meter every day. This would go a long way to understanding how much I use. However it's a lot easier with a device like this. Daily data does not provide any insight into which devices use the most electricity. I expected electric ovens , kettles, and dishwashers to use a lot, but fridges , pumps and motors also consume a fair amount. I can see that an old fridge I have for storing drinks in creates a huge spike every time the compressor kicks in. I can see that my washing machine uses 80% of it's power in the first 10 minutes of operation .

Dales application can analyse the data from the device and provide some insights , for example trending (am I improving) , which days of the week do I use the most (Sunday dinner and Monday wash day are the worst offenders) and when during the day am I consuming the most. This is important as I have Economy 7 cheap rate electricity from 23:30- 06:30 GMT which is 00:30 - 07:30 BST. My spreadsheet calculations are that, with my Scottish Power tariff I need to consume 9% during the E7 period for it to be worthwhile. If you have E7, your tariff may vary, I have seen some where the break even point is as high as 38% !

I am also using imeasure , a a wonderful web site run by Oxford University , for recording your weekly GAS and Electricity readings to see how well (or not) you are doing against similar types of property. It even gives you an A-F energy rating, just like the ones you see on White Goods. Currently I'm an E , which I'm not happy with, but all this analysis is helping me improve that. More to follow on this subject

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 ma

Bracing IKEA EXPEDIT or KALLAX cabinets for greater rigidity when used with a turntable

The inevitable problem, too many records. Turntable and amplifier on top Like many record collectors around the world, I have a number of IKEA cube cabinets from both their EXPEDIT (older) and KALLAX (newer) ranges. These are easy to make, cheap to buy and perfect for record storage. The system comes flat packed and uses bolts and dowels to hold the system together. If you follow the instructions  the system is strong and should not collapse. You can augment the joints with PVA wood glue for extra strength. My turntable sits on top of an EXPEDIT 2x4 cabinet, laid along the long side, with some felt feet to support it from the floor, and you can use KALLAX in the same way. It's been great but has two problems I wanted to address : 1) Because the system has no back panel, the records  can be pushed too far back. 2) While the structure is strong and fairly rigid, there was some lateral movement. With heavy equipment on top, I found that if I nudged or knocked either top side, this all

a vintage Sonab 85S / Yamaha CP-500 turntable

The Sonab 85S turntable You'll see from this blog that I'm interested in vintage audio equipment , especially turntables and speakers. I keep an eye on ebay for potential bargains, and saw this turntable listed quite close to me and for a very good price, £60 buy it now, including 45 adapter, dust bug, DIN adapter, record clamp and a very nice Shure M95 cartridge. Condition listed as very good and with the original sonab headshell. I've been interested in this deck for sometime, as to my eyes , it's a particularly nice design, with the very simple tonearm and deep chassis. I was aware that the model , from the late 70's was a cooperation between Swedish manufacturer Sonab and Yamaha. I don't know how much was contributed by which firm, but the same deck, or one very similar is also to be found as the Yamaha CP-500, though typically in teak rather than black. There were two Sonab models , the 75 and 85, the former being a manual  deck, the latter an automatic, an
