THE FISHER K-10 SPACEXPANDER - VINTAGE SPRING TUBE REVERB UNIT. Found this in the basement of an estate… It had all the original packaging from what it appears. Not sure that it had ever been used. I have tested operation. All tubes glow and the unit produces sounds when the springs move. I do have a video of it working, I just cannot post it on here. Thanks for looking!
