Toshiba SB-404 amplifier

Technical Features

The all stage direct coupling OCL (Output Condenser Less) type IC amplifiers (output music power 68W) are installed in all the four main amplifiers to increase their performance and reliability.

When used with two speakers and a BTL (Balanced Transformer Less) connection, approximately twice as much power is obtained, than when used with only one speaker.

All the two channel program sources (record, open reel, cassette, cartridge tape, FM broadcasting, etc.) can be reproduced in the four channel fashion with the built-in QME (QM Effect) unit.

This stereo amplifier has a built-in special condenser-cartridge (model number C-401S) amplifier and consequently can be directly connected to the player, and further can be switched to the magnetic cartridge with the aid of the switch.

The level of each channel can be easily adjusted, because the accurate detection of the level of each channel is made possible by the four built-in large scale level meters.

The low-noise transistors, which are produced on the basis of the PCT manufacturing method developed by the Toshiba, are used for all transistors in this amplifier.

The reproduction of all the channel program sources is possible with this unit because two systems of input terminals for four channels are provided.

The four channel tape deck can be also used with this amplifier.

Two channel headphone may be used as well as the four channel type, (model number HR40) utilizing both the front and rear headphone jacks provided.

Condenser-Cartridge Amplifier

There are two types of cartridge, the velocity proportional type (MM, MC, etc.) and the amplitude proportional type (photoelectric cartridge, etc.). The condenser-cartridge belongs to the latter type and a special correction curve different from the conventional one is necessary. The power for the ICs in the cartridge is supplied through the ground of the input terminal R channel. This amplifier can be directly connected with the condenser cartridge (This is not the case for the photoelectric cartridge).

BTL Circuit

When the four channel amplifier is used for reproduction with two speakers, this circuit is used in order to operate the four amplifiers effectively. The output voltage of two factors of magnitude can be supplied between the output terminals of each amplifier when the one speaker is operated in phase and the other out of phase with the use of the phase reverse circuit.

Although the output power is theoretically of the four factors of magnitude from the relation, —(2V)?/R=4V?/R, that is in practice reduced to about two factors of magnitude due to losses such as the regulation of the transformer, the emitter resistance, etc.

Toshiba PT-490 cassette tape deck

 Toshiba – Now you can record on a Dolby cassette deck for 2 straight hours without flipping the tape.

Recording Beethoven’s  4th, 5th and 6th on one continuous taping. Or playing a two hour tape of The Beatles without even being in the same room. Or catching yourself in duet with Brubeck and not having to stop flip the tape. Well, if your cassette deck is a Toshiba PT-490 with the automatic reverse feature it’s easy.

Just set the Mode dial and the machine knows exactly what you want it to do. Whether you want it to record one side of the tape and then stop. Or play and turn itself off. Or record both sides of the tape for two uninterrupted hours. Or play back the same tape indefinitely. The machine does it all for you. And it does it automatically.

In addition to reversing its own tape, the PT-490 also gives you outstanding performance and sound. That’s because it comes with Dolby noise reduction. Mechanical auto shut-off. Separate record and playback volume controls. Two large, illuminated VU-meter. And a bias selector switch for normal, hi-fi and CrO₂ tape. And it’s one more example of the fine craftsmanship that goes into all Toshiba products.
