Vintage Extremely Rare Sylvania SuperSound Series GTE Amplifier/Speaker

Description

Sylvania SuperSound Series GTE Amplifier/Speaker. Condition is "Used".
It’s nearly impossible to find any information on this thing. Or even it’s worth. The only information I found on it was through a popular mechanics magazine from the early 80s just before Sylvania was sold. It stated that this was apart of a “SuperSound Series by Sylvania that would connect to television sets to create true high fidelity sound.” If anyone has any info on it please let me know. Product powers on. I Have not soldered any speakers to them to test their functionality. They’ve hardly ever been used and it’s been sitting for awhile out of dust and harm so they should still be good.
