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 ...

mending loudspeakers

Having been interested in music and audio equipment since the late 70's, I hate to see old speakers go to waste, especially when they classic British vintage designs like Wharfedale, Leak, ,Mission,Celestion etc. I subscribe to freecycle and sometimes I see old speakers come up on there, usually because they are damaged in some way. I'm no expert on this, but have managed to cheaply get some pairs back to working and presentable state. It's actually not that hard. If certain collectable brands ever came up (i.e Tannoy, Lowther) I know enough not to attempt this kind of "get you home" repair and would consult the experts. The speakers described here are high quality models from the 70's/80's that were produced in large numbers, and while very good, they are not that valuable. The Leaks The first pair I got from freecycle were a pair of 70's vintage Leak 2020 sandwich speakers. The term sandwich refers to the technology that Harold Leak used...

the curse of the GU10 halogen bulb

I know more than I want to about these light bulbs. While the UK Government is waging war on the 100 watt incandescent light bulb, they have, typically, ignored the growing trend of using these bulbs. I guess they pay people to change bulbs for them. We had our house gutted and rebuilt in 2000, and as a consequence had around 40 recessed lights fitted, each of which take the GU10 mains voltage (240v) GU10 light bulbs. At first, the main issue was that the halogen bulbs had a very short life span and cost a lot to buy, around £5. I seemed to be changing a couple a week. Things have improved and now the bulbs are relatively cheap ( £1-£2) and have a fairly long life expectancy. So what is my gripe ? Well these bulbs are rated at a hefty 35 or 50 watts. The packaging even implies that they are energy saving in some way, but of course watts are watts. i If you have 5 * 50 watts halogen bulbs in your kitchen, then you are using a unit every 4 hours they are on. If I turn on all th...
