NAC72 Selector Switch knob not working...
Posted by: VinBob on 03 October 2015
Hello All,
Hoping someone can give me some advice here - I went to use my NAC72 this afternoon and noticed that the input selector switch just turned and I was not selecting any of the inputs - that is, it wasn't making the usual clicking sounds as you turn to go up and down the inputs.
I opened the selector switch and believe part of the screw that locks onto the selector switch rod has broken - I am trying to remove the screw to replace with another (if I can find a match) but struggling to remove it completely.
Has anyone come across this dilemma and is it as simple as replacing the screw or do I need to replace the entire selector switch at this point?
Hope I have explained this clearly and thanks in advance...!
Cheers,
Vin.
@vinbob - If you keep trying, I believe you will find a suitable screw (!!). Its just an engineering part - so its out there, somewhere. Regarding costs, whats your 72 worth...? Compared to the cost of say 10 screws...? Worst case, someone in the UK might help you.....

I hear ya Ian... Not that I wouldn't order them given the cost, but I just thought it was funny that I would have to pay 3-4 times than the actual part.itself...
.
@VinBob - So the part is cheap....?? And you are a long way away.....
In a former colony. I rest my case.
I sometimes wish that the shipping cost from the US was as cheap is it is from Europe.... Or as fast.
Yep... I guess it works both ways....
And the golden rule: strictly no sales or wanted ads, including offers of free stuff etc..
I’ve looked at the rules and I understand why you don’t allow sales of, loans of, or gift of equipment. But the term equipment obviously refers to an item of hifi equipment, IE. CD player, amplifier, pair of speakers, tone arm etc. not a single grub screw, which I don’t consider to be equipment, more a single piece of mechanical hardware.
I thought you’d edited my post because I mentioned I’d modify the screw by reducing the head diameter. Although to be fair you are in order, due to the fact it hasn’t been tested and sanctioned by Naim HQ. 
Hello All - So I placed an order for 10 x 6BA 1/4" (and 10 x 7BA x 1/4" just in case!) stainless steel screws - hopefully between these two, I should be good and will have plenty to spare! 
Will let you all know how it goes once I get them hopefully late next week...
Thanks again for all your help/support...!
Cheers,
Vin.
Helo All,
Just to close the loop on this one and I am a Happy Camper again!
The 6BA 1/4" screw is the exact same one that Naim used way back when. I was able to get the replacement in and made sure it is screwed on nice and tight and all is working again with the original knob.
Thanks to everyone for your support and help on this - couldn't have done it without you and especially fatcat!!
Cheers,
Vin.
