I enjoyed working with Exogal as US Sales Manager and helping support dealers.
I had made a copy of the old website and put it in a subdomain of another site I have:
https://ttsetup.com/exogal
Support files previously only available to dealers can be accessed through the Dealers page.
It's the best I can do to support people who own the products. I've been in your shoes and wish you many years of listening pleasure.
