AussieAmplifiers NX150 Spyder

[Pocoyo]

Hiii ... my first experience to build my own amp

For everybody who build this amp NX 150 Synergy mofset
you can join with me, maybe we can help each other to
make this pcb and component to be a perfect amp

Maybe i will blindtest this amplifier too with picture in the
thread for member and i will tell the truth is this amp ok
and what it is characteristic

This all craziest hooby start when i hear we're alone from
Rita Coolidge in my friend house he just use Rotel 1072,
Marantz and KEF speaker ... How wonderful

My education was accountant and marketing i had experience
in electro before when i was in junior high. We make LED Radar and no one lamp is on

So i begin to look diyaudio forum in january 2007 i look all the solid state and digital i look from the beginning. Nice idea

Finally i contact Anthony E Holton To Make this Spyder and
this is the photo when he came with fedex

I will continue tomorrow ... Stay Tune

I buy PSU PCB from Anthony Too
but i have a little trouble now

can you help me guys, i can use
- 6.800 uf 63V / 100 V
- 10.000 uf 63V / 100 V
but the caps diameter max is 35 mm

can you help me to choice the caps for this psu
and if it is special caps
please let me know where i can buy it

If i use Blackgate it is good or just waste money here
please dont lie to me

[Pocoyo]

anyone help me for psu caps

[Pocoyo]

After I googling some website i found
some seller who sell cap 6800uF 63V
10000uF 63V and 10000uF 100V.

I found some Nichicon Muse FW 6800uF
63V from the seller in Taiwan. Even i dont
much interesting with this caps but can
be a back up if i dont find better caps

caps is very cheap @ US $5 because it is
bigger size so i buy all his caps 20 pcs

Maybe the caps in the shipment now
i hope this will good for my Aussie PSU

Regarding Big Electrolytic Capacitors for Amplifier Power Supply:
----------------------

You do not have to use BRANDED caps.
They are usually considerably more expensive.

What you pay extra for is most 90% 'the label'.
The plastic wrapping appearance.



I buy good industry standard cpacitors, from Taiwan.
Low price factory line.
Price is lower per / uF, and I do not expect them to inferior.
In fact they have data that can compare
and sometimes even be better than ELNA.
ELNA is somewhat of high quality industry MARK.
It is a good quality to compare against.

You should look for data, like:
- lifetime of cap at 85 degrees C
... there is a 'more strict norm' at 105 degreees C ( but 85 is enough for most apps )

.... some are called 'longlife'
but best is to make a compare of this in the 'worst case data'
which should be specified for any Serious Capacitors.



.................................................. ................................

It is a bit like with your JEANS:
jeans can have label: Levi's, Wrangler etc.
But jeans costing only 50% of those can do as good for you!

It is a bit like with your SHOES:
shoes can have label: Nike, Adidas etc.
But shoes costing only 50% of those can do as good for you!


... maybe I am barking up the wrong tree here:
all reading this post, are wearing Levi's jeans and walking Nike shoes
besides having their pockets full of hard cash
... they just don't know how they can spend all that money


... and will not use anything but leading fashionably latest caps
... you know those that can have dark color in name ( read my lips: 'black' )
.. but in reality can not show you any significant better data
...if you even can find datasheet online

I just kidding to wear the "black" in my psu
board the first reason is their diameter was
40 mm ( for 10.000 uF 63 V )

In bottom of my heart, i believe
BG has top formula and better performance

The PSU board can receive caps diameter
only 35 mm

I talking to anthony too and he give another
idea but for that item i been search for a long
time ... never found it

This is Ni FW 6800uf 63v for my back up

[Pocoyo]

because in the psu we use some caps

why we dont buy alot if it is cheaper ?

maybe we can give to other friend, so he
will start to mods his audio

after that we teach him to buy expensive thing
so i just listen and no need to buy it myself

just give him cheaper caps

[Pocoyo]

This is the first time i got bonus

free caps phillips for nichicon FW
( 22 uf 63 v ), thank you

Maybe if i buy BG Std the bonus is BG N

Hi Jeffry,

Your nichicon FW looks tiny , you better check the datasheet to make sure the ripple rating is sufficient.

Hii Hartono, where are you ?
this is my HP number 08158772900
go to sms man

After i measure my caps and looks the nichicon diagram
http://www.nichicon-us.com/english/s...ini/daia_f.htm

The size is right 25 mm x 50 mm
( I buy cause when i look AE Holton Psu space is 30mm )

This is very cheap wanna buy it ?
