I thought that was probably what you were going to say
The only thing that I wondered about was that most domestic type sponge products now are designed to degrade quite quickly and don't really want to be repeating this "delicate" and "highly technical" operation too often.
Oh well if there isn't a special non degrading type, £ shop scourers will have to do.
I am a little concerned that your posters keep refering to this turntable as vintage. As I've owned it since the early 70's I'm guessing that makes me vintage too.
Thanks for your reply.
