I've recently taken up the task of resurrecting this old gem: Sanyo VTC-R4ME.
Originally purchased in 1983 in Saudi Arabia, this unit worked pretty much flawlessly until the late 90's. I'm currently diagnosing some issues with a board which I believe is a secondary power supply or power regulator board.
I'm being very cautious as I still haven't been able to find any service manuals or schematics on this model.
I'm posting this mainly just to show off this old reliable beauty and the insane amount of work that went into it's construction. Having said that, if anyone does happen to know where I could get my hands on any kind of documentation, I'd appreciate it
