¥ 25,000 (around 1970)
Commentary
Dedicated adapter that can increase the number of channels for multi-amp playback by combining with TA-4300F.
By adding one TAD-43F to the TA 4300 f, a 4-channel multi-amplifier configuration can be developed.
It is also possible to make a 5-channel multi-amplifier by adding another unit.
A TA 4300 f 4-channel adaptor is used for connection.
The circuit configuration and performance are equivalent to those of TA-4300F, and excellent characteristics are obtained by high-performance FET.
* The 4 channels described in this unit are 4 channels of multi-amplifier configuration, not for multi-channel playback.
