SONY TC-255

Commentary

This is a tape deck that omits the speakers and power amplifiers used in tape recorders to connect to your own stereo equipment.

Uses a 2-micron head.

An anti-vibration type motor has been adopted to reduce vibration and noise from the mechanism itself.

A total of 13 silicon transistors, including four high-gain transistors 2SC631, are used in the preamplifier section to reduce noise and the recording bias frequency is set to 160 khz to reduce noise.

With an escalation drive mechanism, the pinch roller lowers when the control lever is in the stop position so that the tape can be easily mounted without getting caught.

A vibration prevention roller is used to absorb the micro vibration generated at the contact surface between the tape and the head.

Equipped with an automatic stop switch, the mechanical power is automatically turned off when the tape is finished.

Equipped with a 4-digit tape counter.

You can temporarily stop the tape being recorded or played. Also, moving the control lever to the stop position cancels the temporary stop.

It has a headphone port.

Since the recording lever is independent for each channel, monaural recording or sound-on-sound recording is possible.

Equipped with a DIN terminal.

It can be used horizontally or vertically, and the wooden cabinet can be removed and incorporated into other consoles.
