The autotek isn't anywhere close to being the same as the earthquake.

ZED made old Hifonics and old Autotek among others. Earthquake of San Francisco got sued for copying those ZED designs and building them in Korea and reselling them here in the US. < as I recall it was a copyright infringement claim > It was actually good advertising for Earthquake back in their beginning in this business. ZED amps were hot and the court stuff just added to the publicity of Earthquake.

Never heard about any settlement though.. It was news a long time ago here in the SF bay area.... Series VII era stuff...Oh I have a series VII on my bench in front of me right now Woo-Hoo...easy money !

So yes there are Earthquake amps out there that are very much like ZED amps, almost clone copies....and there was some lawyer time spent over it....

Hope this "OLD" news info helps...

What would one of these Earthquake PA-2150's be worth these days ... I have one I might consider selling.

As far as my knowledge went though they were USA made.
