Access-312 Build Thread

[Rellister]

Did anyone build this with DOA sockets available in Europe? Farnell, RS, etc...
Digikey is charging alot for shipping to Europe just for these sockets.

 

[3nity]

look at the specs at the mill-max and look for something available in europe.
I never thought about it before.

 

[sr1200]

did you try getting them from whistlerockaudio?  I used those on all of mine.

 

[Rellister]

Thanks for tips. Tried finding something similiar at Farnell, but their selection of sockets is a little limited. Will check out whistlerock, those fit the board nicely?

 

[sr1200]

Ive used them on 8 boards now. all worked fine.  The CLASSIC API ones are the only ones I think that wont fit the holes (or so i read somewhere... doesnt make it true)

 

[buildafriend]

I used 4 classic API GAR discrete op-amps. just get the proper stand offs or whatever those little pins are.

I should have built 8...

assuming shape as the evening wore late

 

[atticmike]

Can you tell how much this build needed again?

17.5 or 18 V dc?

How did you get them to fit without drilling  ???
They are too big for 3nity´s boards, I just received a bunch...
Guess its the digikey route anyhow.

 

[sr1200]

The pins from whistlerock fit exactly, no drilling needed.

I have used 17 V for my access-312. Seems to work fine, and with a good amount of headroom (at least in my opinion) :

I used EA2622, EA2503 and gar2520.

Almost finished my second 4 channel! Love this thing ;D

Mine don´t :-\
Strange.
Maybe we misunderstand each other, we´re talking about sockets, right?
I´ll just order the ED5021.
Want to get this one going

 

[sr1200]

yes the little "holes" that the millmax pins on the DOA go into.  The ones from Classic API didn't fit, the ones from WhistleRockaudio.com fit no problem.

 

[Rellister]

Yes, I know what sockets are
Don´t want to be a PITA here - but this is not correct.

I´m sitting here with sockets from whistlerock and the Access-312 boards in front of me - and there is no way to get them into the holes unless I drill them bigger or shrink the sockets about 0,5-1 mm with mind force.

Its just sockets - so really no big deal, but as long as this info is not correct, I just want to point it out. You might have another revision or something, I don´t know, but they sure as .... don´t fit my boards.

 

[sr1200]

Unless WR changed the parts they sell since I got mine (about a year ago now), I had no issues. 
Sorry if my post sounded condescending, just didnt know how else to describe it.  :-[
Was trying to see if i had a pic of the sockets from my build but all the pics have the DOA's plugged in.  I do remember them being a tight fit, but not so tight that that they wouldn't fall out if i turned the board upside down without soldering them.

EDIT: as long as you have conductivity after you adjust the hole size you should be fine.

Hi guys unfortunately Whistle rock changed his sockets part.
the only way you can fit them is drilling the holes ..thats what i tried and it works.
tip: if you drill the holes when soldering the sockets insert them in a op-amp to make sure that they sit right.

Good luck people.

Thanks

 

[3nity]

Guys i still have 4 boards left in already packed ready for shipping.
Remember last 4...im asking 85$ shipping included.
Thanks.

Do you think it'd be too much if I turned the 12V rail down to 6.something V ?

Also, how do I have to turn the trimpot in order to have it lowest possible for the first power up? ccw?

--

Other than the swap of R4 to 100R and R5 to 10k, everything's correct of the V2 bom?

Did you actually finish the bomV3 @3nity?

I'm not sure where you got that info but the truth is that I never changed the sockets.  I've been selling the exact same MillMax part since I started offering them on my site.  They are a press-fit kind with little ridges to dig into a 0.078" hole.

Cheers,

Mike

Hey Mike,

Did you get my email?
