volume pot and / or capacitor change are possible to diy (not by me i hasten to add, but those skilled with a soldering iron).
the cost of the parts is small, it's just the skill and time to change them, and the possibility that the problem may lie elsewhere and / or a PCB may get harmed in the process.
a bit of contact cleaner is a good first pass.

Hiya! I've a NAD 314 amp, had it forever (uni years, treated myself after summer job, really good deal as it was an ex-demo, etc).
It now leaves at my parents and when I visit I play my old CDs, and when the turntable was still working (planning on fixing that too), the vinyls I've not yet brought back home.
The NAD 314 and similar amps from that brand don't have the reputation to last forever like the bomb proof old Japanese amps, if I'm not mistaken. So my one has started doing funny noises today. As I'm here on holidays with the kids it's not like I've had the time to analyse the issue much, but I think the left way (typical I believe) collapsing/cracking, and unless it has something to do with the source, it's probably about to die.
I realise it's not a particularly sought after piece of hifi equipment, and that it may not be worth the effort, but it's a nice sounding amp (to me) and I'm too sentimental to not even consider fixing it.
If it turns out to be indeed the usual left way fault, what's the fix and is it something DIY able? Would it be pricey?
