NAD C320 Amp - repair or bin?
Discussion
Dear All,
First post in this forum and just after a bit of advice.
I have a faithful old seperates system for the home office, consisting of a 10 year old but (until recently) perfect condition NAD C320 Amp, Yamaha CDX model CD player paired to a set of B&W DM 601 speakers. It is just the job for the room and the system has worked perfectly for many years.
A week ago I had a problem in that when switched on, the amp for a short second shows the green power light, then a click sound and defaults immediately to the red LED - protection mode. It hasn't been played at very high volumes so should not be an 'overload' issue.
I've disconnected the whole system and just plugged the amp into the wall to check power and the exact same default from green - 'click' - straight to the red protection mode. Zero knowledge, but I suspect an internal fuse / relay?
Is this something that perhaps could be repaired cheaply (the amp is worth very little in todays money)? Anyone with experience of how much a repair would be or who to use - I'm in Bristol / Bath region? Is it something I could sort myself, no electronic ability but happy to crack the lid and have a go if the cost of repair is untenable?
If its time to let the amp go any suggestions for a cheap and cheerful amp for the Yamaha and B&W's - will probably go for second-hand e-bay bargain (another from the NAD range, Cambridge Audio etc).
Appreciate any help.
Cheers, Grant

It'd be worth cracking the lid and checking nothing is obviously wrong inside, blowing out any dust and looking for foreign objects eg something near the speaker terminals causing it to short out and go into protection mode
Not sure what could cause a short, but free fixes are the best fixes!
PS before opening it, unplug it and leave it off for a while and try not to touch anything near where the power lead goes in

Un plug from mains. Open up and observe. Fix and quick cheap problem (fuse etc.)
In event you cannot see problem either put on e-bay for some other mug to try and fix or re-cycle it along with other electronics at the tip. My brother once thought he would fix his Nad 3020 amp using his knowledge and degree in physics. He binned it in the end when he worked out that the rate of pay he was on (double time for shift work)would more than pay for a replacement. Time is ££. Unless you have both the free time and the knowledge there is little point mending basic electronics that are relatively cheap to replace.
