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 ...
Repair a Thane H2O X5 Steam Mop
I volunteer at a couple of Repair cafes in the UK, and we have had a couple of these popular Thane H2O X5 Steam mops in with similar symptoms and fixes.
These devices generate steam from water held in a chamber and direct this to the head, to which a mop cloth can be attached. This steam is hot enough to break down dirt, grease while killing off any bacteria. The owners loved them and were very happy to get them working again.
The failed units no longer pumped water through the boiler chamber , and hence generated no steam despite the power light coming on.
The units will suffer with lime scale , as any electrical appliance that boils water will. However the "Catch 22" is that in order to pump a descaler through the pump to descale it, you need a working pump to extract water from the main reservoir via its umbilical hose.
I did a bit of googling and found this video from the always excellent bigclivedotcom
Clives video is the key to fixing these units.
First you need to disconnect from the mains and remove the handle which does not contain any power. It's also useful to remove the triangular cleaning head. To access the motor you carefully need to remove the rear panel. This was held on by around 8 screws, several with HEX fittings. This then enables you to very carefully open the unit
Inside we see the pump and the insulated steam chamber. Note the pump has two pipes , one at either end
a close up on the pump with its retaining screw removed. Once out you can remove the black retaining clip that holds the pump in place
With the black retaining bracket removed we can see it's very similar to the pump in Clive's video
First we need to remove the silicone pipes. I used tweezers to open the clips
Be careful, I found it very hard to remove the top (brown in the picture) pipe without splitting it and in fact needed to order a length of replacement hose online, having split the pipe in extraction. There is not enough slack to allow you to cut off even a short split section
now I can unscrew the inner section of the pump
gently remove the core
the moving part of the solenoid pump
photograph the O ring positions
separate the parts and immerse them in a descaler such as white vinegar
be very gentle with the spring loaded part of the solenoid
more washers and O rings
Descale all the parts, then rinse in water and reassemble
I made good the split pipe with some new silicone pipe , end-to-end. The size is 4mm inner diameter, with a 2mm wall thickness. Carefully refit the metal retaining clips to secure the pipes in place.
Once I had put everything back together, I ran some water through the steamer to prove that the pump was now able to pump water into the insulated boiler chamber. Once this was done I refilled the water reservoir with a descaling solution of acetic acid, or white vinegar and run the machine in bursts, so that descaler was pumped into the chamber , then allowed to work , then replaced. I did this over 4 hours with a few minutes on , then left off for 20.
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...
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 ...
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...
