I used some masking tape just to mark the area that needed to grind down. You will have to go about as deep as the microUSB opening, around 23mm or so.

I took out roughly 1mm or so in material, basically half-ing the overall thickness.

Now the DIP8 opamp sitting flush inside the case without bending the PCB or applying any stress.

Hi ClieOS,

I used a MiniCraft rotary tool with small diamond bit to do the initial sanding down, followed by a small flat file to smooth down the surface. Dremel is probably easier to find than MiniCraft.

wow....i dont have any rotary tool...if only use the file tool...i guess i might need some times to finally make the 1mm depth..

aluminum is pretty easy to grind. get yourself a good aggressive file, start with the edges and than do the middle. pretty easy...

I'm afraid to say, but as far as I can tell from the photo you've uploaded, they are fakes.

The shape and the color of the markings are slightly different from those of legit ones.

The color should be gray, not white.

 

Here is the photo of a legitimate MUSES02 that I bought off of akizukidenshi.com,

an authorized reseller.  (see http://akizukidenshi.com/catalog/g/gI-03417/)

 

 

A legit muses02 has very soft leads, so if the leads of yours are as hard as other standard

JRC op amps like NJM4580, NJM2608, NJM5532, NJM2114 and so on,

I guess they are remarked NJM4580s because they have the same circuit as MUSES8820

and MUSES02.

With such a small picture (not yours, but hkfriends') to look at, I won't dismiss them as fake that fast. It could be just the lighting and angle of the photo that makes it look that way. Maybe we can get a bigger picture?

other than that..they are many buyer review on the muses01/02 they bought from this seller..

The picture of the logo looks FAKE
post #552 of 2235

so i bought a bunch of opamp from element something web shop opa627 and stuff.... it turns out i need to solder on blank PCB... I think I will need to take them to shop... I know it is totally against the DIY spirit... but I thought i would confess earlier...

post #553 of 2235

Haha, I actually soldered a bunch of opamp a few days back myself, still waiting for the BrownDog adapter to come before I can finish them up. Basically I have the OPA627 inside my E12DIY now, which I won't say is better than MUSES but certainly hold its own ground.

I'm afraid to say this, but I'm pretty sure they are fakes.

The font face looks slightly thinner and smaller.

The arc at the upper-left corner of the logo is too round.

The nose looks a bit pointy.

The same date code or lot number "901" is suspicious enough.

 

Here is another close-up photo of another piece I have.

All surfaces has the same texture.

There are no sharp edges around the top surface.

The top surface of a fake one must have a slightly different texture

because it has been ground.

Thanks for commenting on the OPA627. I've been curious as to how it sounds in this amp. Your initial comments are very positive.

Did you use the side-by-side adapter? Photos would be great whenever you have a chance.

More info about how they compare to the Muses would be great! Whenever the time is right, of course.
