I will change the current cartridge which is an A&M for an Audio Technica. The phono lead and plugs will go for higher quality ones.
I also was thinking of changing the Tandberg plinth, which is of a rather poor quality for a nice solid walnut one. For the time being I have placed a foam sheet under the plinth and that has made quite a decent difference.
Starting the refurb and replacing the plinth.
1. Firstly the aluminium top cover must be removed. It is secured by double-sided tape, but in my case it was some sort of glue. This has to be heat softened to gently release the top aluminium sheet, I used a hairdryer.
2. Then with the plinth removed, I placed it on an upturned table so that later I will be able to get at the three suspension springs and adjust them to a satisfactory standard.
3. Once the top sheet is removed you can undo the 5 screws that hold the turntable to the wooden plinth.
4. Cleaning off the glue left on the top panel using white spirit.
