Ortofon TPO-70 (ca. 1982)
Little is documented about the Ortofon TPO-70. What the record shows comes almost entirely from a single period review. The TPO-70 is a moving-magnet cartridge wand, reviewed alongside the Thorens TD115 turntable in Audio (December 1982, p.62-66). The review's specifications list an output of 3 mV at 1 kHz (5 cm/s reference level) and identify it as a moving-magnet design. It appears to have been intended as the dedicated cartridge wand for the TD115's tonearm, not a standalone universal headshell. The review cautions against using a heavy mat or center weight with the combination because of the turretable's light suspension.
Beyond that Equipment Profile, the TPO-70 does not appear in Ortofon's better-known product families (the 2M series, the OMP line, or the later T-series). No separate spec sheet, service manual, or sales literature has surfaced. Its exact production run and original price are unrecorded.
Known specifications (from Audio, December 1982):
- Type: Moving magnet
- Output voltage: 3 mV at 1 kHz, 5 cm/s
