Yes I have one. It is a gem.
It was a complete wreck when I got it. Yours looks really nice and very nearly un-touched in comparison.
I had to strip it down completely and reform the chassis, its much thinner and smaller than the STA15s, and was badly bent. Also one of the output transformers was dead, but Will at Radford Revival made 2 new ones for it. There is a AOS thread about it here:
