The RCA models 8-STP-1 and 8-STP-2 were used with Companion Speaker Units SPK-1 and SPK-2. They were stereo playback units only, designed for use with pre-recorded tapes. As such, there was no recording heads or associated circuitry.
The STP-1 (pictured) was a portable model while the STP-2 was built into a consolette.
The recorder(s) had in-line (stacked) heads and push-button controls for fast forward, rewind and two play buttons – one for stereo and one for mono.
A four-stage stereo amplifier provided 2.5 watts per channel. The left channel speaker was accommodated inside the recorder while the right speaker (SPK-1 or 2) housed a 6½” and two 3½” speakers.
