You can get it here : http://www.analog.com/en/prod/0%2C28...8620%2C00.html as free samples

Free samples, is it really works ? I click Buy online on that site, then I have to register, I follow the instruction. But then I have to enter a VAT ID ? What is that stuff ???

I wouldn't abuse the samples programme like that though.

You can get it at RS Components:

RS Stock No. 497-0975
Part No. AD8620ARZ

The smoothing capacitor swap didn't do much difference to the sound in my opinion. But I had some spare 3300uF/35V Panasonic FC low impedance types so why not?

I received my ad8066 and ad8620....I need to practice the SMD soldering first with an unused old Sound Blaster AWE card.
At last, my 5400 comes alive !!! I think that It already break in after I run it nonstop for several days. The sound was great, it can produce better bass and clarity now. Those BGs and Silmics upgrade really work.
I tested it with Diana Krall's "Girl in another room", the acoustic bass became so powerful and the cymbals are smoooooth.....I can almost hear the sound of the drumstick....
Next plan: add some bypass MKP on the electorytic caps on the output stage, replace the caps of the digital section PS, replace the opamps and perhaps replace the coupling caps with good film caps if I can get some room for them.
Next target : my Cambridge Azur 640A.....

Sorry, what I really mean is those huge yellow coupling cap. If they're really good, I plan to replace mine with some Audyn MKP 10 uF.
Anyway, I'm agree that PSU cap mod didn't bring a significant improvement...

Thanks for that. If you don't have a means of decompressing .rar files:

May I know what caps and what values did you use as a bypass for the V+ and V- of the AD8066ARZ ??

Cheers,

Sounds good.

So, what did you do now? Cut the clocks near the two chips and solderd the clock output directly to the pins? So you used the 16.xx Mhz clock? Where did you get the supply voltage from?

Oh well, I guess, I'll wait for the pix

I also wanted to use the XO with a slightly modified version, using a 2.2 mH inductor in series and a 2200uF/0.1 uF in paralell with the 7808 as an extra filter.

I guess, I'll order the stuff tomorro if we have do new order at work, together with the opamps and some new caps and stuff...

I'm really excited!

Edit: what the hell happend here

A whole bunch of posts has suddenly gone...!

Edit2: Ah, some split the threads.

Hi,

I've been trying to follow this thread but does anyone have a link that I can follow to download the service manual that isn't broken ?

Cheers,

Jon
