I've just started to relearn electronics after 35 years, so I have a soldering/hot air station and a multi-meter, so I am going to attempt a repair,does this sound like bad caps to you guys?

so I opened it up and had a good look, but could see nothing obvious, not to much gunk, no bulging caps,no corroded resistors
anybody have any thoughts?

Hey Lorez22,

you should definitely try replacing the two capacitors in the middle of the bigger board (should be 1000uF 35V) and while you're at it, measure the resistor between the two big capacitors on the same board. Does it still measure with 2.2k? If not, replace that too.

That's what I did yesterday and it completely fixed my static/crackling noise.
(I live in the Germany and my noise was at 100Hz)

For the faulty volume pot, I have to quote Stephen Scutt from EEVblogs comment section on YouTube:
