Commentary

Pre-main amplifier with 60Wx2 output.

As a change from SA600, the tone control is independent on the left and right.

The configuration of the SG520 and SE400S has been simplified with the basic lines left intact, and the equalizer circuit used in the SE400S is not included.

Equipped with a loudness control and oral balancer (NULL BALANCE).
