Over the last few days, my CD70 crackles whilst playing CDs. I've tried changing discs, crackle stays. Radio, crackle goes. CD again, crackle returns.

Weird thing is, the crackling only starts when I've been driving the car 15-20 minutes.

I'll do more testing to see if I can identify a cause, but is this a common sign of imminent CD70 death?

(I'm hoping not as I've just ordered a Dension Gateway 300!!!)
