OK got it, there is a slot that is glued in, pry from underneath the plastic.

There is some of that brownish/black glue that looks like it caused oxidation
around some of the ceramic caps, scraped that and now it works but I'm not
convinced that it won't come back.
Some of this glue is known to become conductive with age, anyone know of
a good solvent to remove it from the circuit board?

This thing sounds great when it works.
