Wollensak T-1500 / T-1515

Original Revere-derived Wollensak design produced with various cosmetic and electronic revisions for a decade; the T-1500 was a half-track mono recorder, while the T-1515 substituted a stacked stereo playback head and small second-channel preamp so stereo pre-recorded tapes could be played (recording remained mono). Featured a neon recording-level indicator and a three-digit counter.
