No, they didn’t have a glitch in software programming and accidentally jumbled the file extension vowels!
Nikko alpha iii amplifier popping upgrade#
NZAUDIO recommends the voltage increase to 100v, I wonder if these kits have this upgrade or should I just purchase the three mentioned.Sony’s proprietary Sony Alpha Raw – or ARW – files are not a mistake. I think I will only replace the C531-C533 first, then see how it goes from there.
Nikko alpha iii amplifier popping full#
I am thinking of purchasing a full capacitor replacement kit, I have found two online, one from ebay from Germany and the other on audio high store.

On my amp serial number A3220154 the above mentioned capacitors are found behind the bass treble balance controls. The 'alt scan' picture of the amp looks different to my amp, doesn't seem to have this circuit and some things are in different places, it may be of a later model.

I can only find these capacitors on the service manual download only page 8. I downloaded the schematics, service manual and 'alt scan' for NAD 3020 series 20. If the audio muting button is pushed in during start up the sound is 20db quieter of course, if I disconnect the pre/power connectors the buzz is not present at all, if I wiggle the Caps C531, C532, C533 sometimes the buzz won't be there next time I turn it on, but then returns later. I have this same problem on power up only. Next will be a B model and will use 4X2200/35v FC`s-I love them as I love the silmics. This is the first 3020 with the small 330/35v in the regulator and I can hear no reason to change them to 470`s. The eq sounds very good but I like my remote commander and I really don`t need any tonal adjustments. I`m using a Hlly AMKII connected to the normal inputs(power amp). Now mine sounds like the best amp I`ve never heard. Try not to spoil the amp by arranging them upright and straight. Pay attention to the way the transistors and film/ceramic caps are mounted-it is not done messy by a child although it looks that way. No need for that! (Cheap)Van Damme silver cables internal audio line-no need for jumpers in the audio line and some good speaker cables from the Motos to l601,602 and from the coils to speaker terminals. I found a working series 20 at the dump and have swapped all elektrolytics to what I had in the drawer: raw PSU 4x2200/35v Nichicon fine gold, Regulator 2x 330/35v Panasonic FC+6x47/35 FC.

Now 35 years later I can see that the forest covered the trees. Back then there was HiFi gear everywhere and had to try it all. I bought a 3020 in 1985 paired with some small 2 way AR`s but sold the combo bacause I was young and stupid. I think it does a darn good job overall and is certainly (for the cost) a no brainer when it comes to vintage audio. Now for the downside, the midrange can get a bit muddy and confused at times - it's not as refined as I'd like to hear, but it is by no means a 1K+ amplifier either! I mean, where the heck did that bass come from!!? I was outright shocked with the bottom end.I run a pair of 4.5 fullrange speakers right now & I've never heard an amplifier take control of them as the little NAD can. That aside, it's a splendid little amplifier. It has its quarks, the RCA's on the back are suspect for channel drop outs and grounding problems, and the construction (being a bit cheap) the culprit for bad solder joints (particularly at the speaker outputs).

The little NAD can be described as the little amp that could - gutsy, plenty of drive, ability to drive difficult loudspeakers, and pretty decent sounding. I decided to take one for a spin the other week, I am pretty critical of good amplifiers (having over 70 of them over the years). Today, still very obtainable & functional.
