It's a Sony SLO1700 Betamax I really like these machines a real mix of proven (for the time) electronics mix of the SLF1 and the SLHF100 with extra panels and tweaks to make the profesional duplicator a tough machine.

From the thumbnail, can you tell which machine has the frosted and which has the clear meter lamps? Let me know in the comments.
