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

Fixing a leaking gutter

In the UK  most houses appear to use some form of modular plastic guttering. It comes in different colours and cross sections. Pieces are held up using brackets. Where sections join together a connecting pice is used which clamps beneath the two sections  coupling them together, and an outer clip piece binds both pieces together with a rubber seal as the filling in this sandwich.  The rubber seal consist of a length of rubber strip which sits in a groove in the juntion piece. In the picture above you can see a corner section, below you see a mid section join between two longer lengths. I routinely find persistent drips from these junction points. This is not great as where the water lands you get splashing, which over time can soak the walls close to the splash point. It can also start to damage wooden paint work. if your in a room  nearby a persistent drip-drip-drip is also annoying. So dripping gutters are a bad thing. I have repaired gutters in 3 houses and a Scout Hut I

Restoring a JVC JL-A1 Turntable

Last year I acquired a Pioneer PL-12D turntable which I restored and runs very well. In the blog describing the process I mentioned that I believed that much of the content would be suitable for a wide range of 1970's Japanese belt drive turntables from the likes of Pioneer, Sony, Sansui , Kenwood/Trio etc.  A few weeks ago I spotted another turntable being auctioned locally on ebay. The price seemed very good and I bid for it and won. It was a JVC JL-A1 which I got for a very reasonable £20 and was able to collect. The unit had been in the family from new and was in very good condition. Just a few issues due to age , namely the hardening of both rubber and lubricants with age. I had read in the vinyl engine forum that it was similar to the PL-12 and I wanted to find out, plus I enjoy working on decks. As you can see from the pictures it is very similar.
