Model SPC-2. DUAL AMPLIFIER, STEREO-ORTHOPHONIC HIGH FIDELITY. The tape is housed in a large cartridge that looks like a giant cassette tape. This was early 1958 or 1959 and cost around $300. It records and plays at 3 3/4 IPS. It has a built-in tube amp for stereo playing and recording. It has one speaker system built-in .Stereo recording/playback time is about 1 hour.
