Hi there
I don't know what's happening at Alembic's but I mailed a month ago in order to kwow how much it would cost to have my Series I preamp card fixed but got no reply. I don't mean to ship the whole bass from France to USA, just the card. Anyone can help ?

Not sure what happened to your email, but the price for a PF-6 exchange is $75 plus shipping charges. The preamp card will be either repaired or replaced with a rebuilt one.  
 
When you ship it, send the card in a static-safe bag and then pack the bag in a sturdy box. Insure it for $350 (replacement cost) and send it to:
 
Alembic
attn: repair
3005 Wiljan Court
Santa Rosa, CA 95407-5702
USA
 
Enclose a note that includes your return shipping address, the serial number of your Series I, and credit card payment details. Servicing takes 1-2 weeks plus transit time.

Thank you very much for your advice Mica. This is quite appreciated !
My email must have got lost somewhere in the ocean !! lol.
I'll send my card as soon as I can.
 
Thanks again.  
And once again, congratulations for your baby boy. Hope the family is well !
 
Best regards.
