Im looking for the small screws to close the
electronics at the back site of the bass.
I miss 3 pieces.
Who can sent me some?

I bet Mica can help with the backplate screws.  
 
  Do you have any pictures you can post of your '73
Alembic? It's always a joy to see the early Alembics.
 
All my best,
Kris

Kris is right; for a '73 you best contact Mica and maybe post a pic of the screws that you do have.  For '76 forward, these are the screws to get; but as indicated on that page, prior to '76 some instruments had wood screws for the back plates rather than stainless steel into threaded inserts.

Dave,
 
My '76, born in July, has wood screws.

My 1977 Series I Guitar from March 9, 1977 has wood screws for the back plate as well. Slotted heads. Look like brass.
 
The ones on my Tribute are Phillips head and look like stainless steel.
 
Are all the wood screws brass and all the screws that go into inserts stainless?
 
Todd.

Thanks for the additional data on transitional dates for plate screws!

hi elwoodblue,
 
I can post some picutures, what is your e-mail adress?
 
Best regards,

Kees,
 I sent you  an email.

Hello Kees,
 
I'm not sure if this will help you, but my 78 series one has the older style wood screws and I had a similar problem.  Part of the reason why you may be missing three is because these often seem to strip out from the wood over the years.  
 
I got around this problem by using Tamiya epoxy modelling putty (from a plastic modelling shop).  This is easy to fill the old screw holes with, and you can poke a small hole in it when it is still wet with the sharp end of a toothpick.  worked very well on my series.
 
After this putty had cured (with the pre-formed holes), the screws went in very well and held tight.
 
Just a thought.

Here are pictures Kees sent me,
...and a link to the build record; here
 
It is a 1979 instrument so that should help with locating the proper replacement screws.
 
   
 

....and some more pics:
 
 
 
 
 
 

The first thing I noticed is the pickup height adjustment screws could be reconfigured .
  From the factory Alembics have two screws above the ears of the pickups and two below.  
 The screws below the ears determine the desired height and the screws above hold it snug, you want to be very careful not to tighten the upper screws too tight as that can crack the pickup enclosure.  
 
 Here is a pic of what I mean:


 
 
The screws on the treble side of the pickup are opposite of the bass side , this picture illustrates that well:
 


 
 
...and here's a link to the adjustment procedure:

If you want to take a close-up of the screw inserts under the back plate that would help to make sure that you get the right replacements,
 If the picture is over 150 kb then it will need to be compressed. I'd be happy to do that if need be.
 

Hey, who's been shooting pics of my bass? ;-)

I borrowed a couple pics from the site here to show Kees the original pickup screw configuration,
 
thanks for making it easy Adriaan
