Golden Eagle made these back around mid 80 or so, the company was NOT related to Kenrich, nor Browning. these were made back when
CB was still a huge thing, but on a decline. They also made a 750, and a 200 base, as well as a line of solid state mobile amps.
I doubt you will find much background on the builder, probably a fairly small operation, and fairly short lived. I owned a 750 and a 1K, they would both do well over the rated power output, but the build quality wasn't the greatest, I much preferred some of the other Sweep tube amps.
They were very impressive boxes while/when they worked.
Here are a few pics of others they built... going to hunt through some archived info i have and see what else I can dig up...
