mending things

  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 ...

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...

I'm delighted to receive messages from readers who have found my Pioneer PL12D blog of use. I recently received this article from a correspondent - Dirk Sipes, and wanted to share it. His approach is that of an engineer, rather than my amateur efforts, and there are some very interesting  details around things like bearing material and the nature of the suspension springs. He has also owned the deck for 40 years since new, which speaks volumes about both their quality and his care. Here it is : About me: Readers be aware that I have tried to use names for parts as they appear on the service schematics for the PL-12D that are available on VinylEngine.com, thus bushings referenced in the blog are what I call cushions, etc.   Also, I have provided some locations where products that I used can be obtained.   Those businesses do not even know I list them, and my use does not necessarily represent an endorsement, although I have found them to reputable.   My tha...

A feature of many of these blogs is my interest in vinyl records and turntables. Over the years I've acquired and restored a number of decks, all of which came with a cartridge, but were they worth keeping ? Well my  friend , and fellow fan, Clive,  has created a wonderful resource with a great deal of invaluable detail about a wider range of cartridges, and reviewed in classic decks like the PL12D, Rega Planar 2 and the Technics SL1200. Well worth visiting for the insight and detail around things such as optimal capacitive loading , for example PHONO CARTRIDGE REVIEWS

A good friend recently spotted this turntable, being sold on ebay, buy it now at a reasonable price , and very close to where I live. We had both commented  in the past that the Harmon Kardon T40 was a nice looking deck, with it's deep platter and champagne colour, so it was impossible to resist. Not that well known in the UK, and advertised as not working, with a hinge missing and a burn on the lid. I bid, won and collected it from the seller, who was very helpful , and it was exactly as described. Upon inspection the main problem with the deck not starting was due to the belt having petrified  and broken into small pieces. the motor worked as I lifted the arm across the platter and appeared to correctly eject the arm at the end of side position. The motor turned fine. As well as the drive belt, the 4 rubber feet had also aged badly. As you can see from the picture ,all that remained was the 4 springs and parts of the rubber cup. I think there would...
