I have both, a working D-6C (SM version), recently serviced by Deb64 in July 22 and little used since (about 10 hours realistically) AND, I have two CX20084 chips which I believe to be genuine, I sold 2 to Debbie at the time she repaired mine and they worked at that time, I don't know if that is...

I also emailed Les at Avondale and he pointed out that I should be measuring between + and 0V, not + and - on the Minicap 6, now I have a reading of 35VDC which seems more like it. Yes I am fairly confident that the MM is reading OK, but again I was reading the secondary voltage across the...

Well it's been a long time since I started this thread and about time I did an update then. I have just today removed the NAP boards and the power supply board in my NAP 180 and and have fitted a pair of MINICAP 6 boards and a pair of Qudos boards to replacer the Naim originals. It's not...

I will look at the NAP250 upgrade later I think, the problem is that I have a pair of Olive 250s which intended to use in an active set-up and have never yet heard them that way (I only ever heard active 135s and that was 40 years ago nearly) so I would like to hear them first and secondly it...

Apologies for the delay, work has been a bit crazy recently and I have hardly had time to think about anything else. So, decision made I think, I will upgrade my NAP180 for now with a pair of Qudos boards (just purchased from Avondale) and a pair of Minicap 6 boards that I am still to find (and...

Excuse my ignorance here, is dual mono not stereo ? OK, I know that stereo is not the same information going to each channel but why would anyone want to hear mono these days. If I'm not mistaken the Nap 135s are a mono amp hence the need for two of them in a stereo set-up. It looks as though...

Thanks for the clarification Mike, I'm confused then, there is a clear photo of the innards of a 180 with two of the minicap modules replacing the original regulator board and a pair of NCC200 modules on the AA Facebook channel, it was in 2016 mind you so it's well old and may not be suitable...

Sounds like a plan then, I have been reading up on the AA Facebook channel, well worth a read too. I seems that I can upgrade just the boards for now then, but I have a question about the comment regarding "add regulation to the front end of the NCC200/220 boards, at a later time", I have seen...

That's what I getting at, my 180 is standard and unserviced at present, so potentially without the power supply regulation it may be a little more 'exciting' than the 250. So I am left wondering about what to do with regard to upgrade path one the 180, my worry is that I will potentially lose...

Whilst we are discussing this, am I right in thinking that the 180 and 250 share the same amp board (NAPA6-4 ?) if that is true then what is so different about them and what is causing the difference. There is not much in the way of reference material to look at on this so I would be intrigued...

Thanks gents, Just to be sure, if I bought them and changed them myself there is no need to return my original Naim boards to Avondale (I saw that Naim modifications on the Avondale site talked about them taking your original boards in exchange). I did see another thread where the NCC200, 220...

Hi guys, Apologies if this has been asked previously .... and Happy New Year to everybody I am curious about upgrading either my NAP 180 (second system in Thailand) or one of my 250s (I have a pair which I intended to run active at some point here in the UK) with either the NCC200 or NCC220...

Hi AnilS, Thanks for the prompt reply, I was just surfing Ebay as you replied, there are a few around but not too many decent ones. I am sure it is not a subject much discussed on any of the Hi-Fi forums because everybody assumes that GEs degrade the sound, it's unfortunate really that...

Hi Anils, My apologies for not replying sooner, I guess I just went off and did more listening than typing - always a good sign:) Nice system you have there, a good spread of tried and trusted Japanese with a bit of English thrown in for good measure .... I am now leaning towards a graphic...

Can I assume that the capacitor (6n8) in question is the blue (PP ?) one nearest the 470R resistor at bottom left corner of the board ? and the tantalum caps, are they the larger (marked S.L.C.E) or smaller (red-ended) ones on the board ? One last thing, can anyone recommend a decent...
