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 ...

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, thi...

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...
