SKOL! I don't know. SLM was running the show from '86 until '05 or thereabouts. I don't know if any Ampeg fanatics track these newer market serial numbers. Maybe @JimmyM would know?

The dates are as follows:
SVT-3PRO - June 2002 (also designated as export version)
SVT-15EN - December 2003
3rd photo - May 2001
