I have a TEK 2432A which works fine but shows a slightly noisy trace. This happens on both channels, even when these are grounded. Anybaody having a clue where I should start lokking to repair this?

I'd start with the supply rails. It could be an electrolytic decoupling one of the rails.

There is a very good Youtube video that deals with this issue, #214 Tektronix 2432A Oscilloscope Power Supply Re Cap - YouTube
