SONY TA-F2
¥ 32,000 (around 1976)
Commentary
A pre-main amplifier developed by applying a new power supply circuit obtained in the development process of the TA-F3.
It employs a multi-power filter system with a total of six decoupling filters between each amplifier, reducing crosstalk in the low frequency range.
The power amplifier uses a pure complimentary service all-stage direct-coupled circuit and a dual-transistor differential amplifier that combines two transistors with the same characteristics into a single package.
0.01W ~ 100W direct reading power meter is installed.
Equipped with a muting switch.
