[left]in 1968, Sansui introduced the first solid state power amp, BA-60 followed by BA-90, BA-100, and BA-150.
BA-60 was the beginning of long tradition of BA and B power amplifier series.[/left]

36,300yen(August, 1968 release)

Description �@
Compact all silicon transistor power amplifier developed in pursuit of the clarity of sound.
The distorted reduction at the time of the elongation of a low-pass sound or the Koide power is pursued by the audition testing of not only a data but a repetition.
The output circuit has adopted the three-step hardwired-connection circuitry of a pre driver and a low-noise transistor with a PNP transistor, and has improved the distortion at the time of low-pass or the Koide power, and IM distortion.
Moreover, regardless of the input adjuster, the input impedance is kept constant by forming buffer amplifier.
The dumping factor changeover switch is carried and a more faithful play is enabled by uniting with the optimum value of a speaker drive.
When an output-terminal short-circuits accidentally, the protection network is carried so that a power transistor may not be damaged.
The pure electronic formula PSC circuitry original with an SANSUI is adopted as this protection network, and also the security is improved more combining the immediate judgment fuse.
The headset jack is carried.
A power transistor is mounted on the heat sink of an aluminum extrusion, and the heat-dissipation effect is mentioned.
The speaker phase changeover switch of a right-and-left independency is carried, and the phase of a speaker can be changed with a switchpoint.
If oral one / null balance switchpoint is carried and a switchpoint is carried out to a testing, the series interconnection of the right-and-left speaker will be made, if the balance is maintained normally, sound is lost and a balance on either side can be adjusted easily.
The volume of a right-and-left independency is carried and it can adjust independently, respectively.
The adjuster of input level is carried so that it can be used for any preamplifiers.

·הגיע!חוני כתב:במקום להוציא ולהכניס את כבלי הקישור, אני חושב על קניית 'בורר מקורות' ....
מוצר נהדר!!
