The GAD 300 Amplifier
The equipment is a pure class A amplifier, it does not contain any feedback circuit.
Since there are separated power supplies for both sides, there is only a minimal
interference between the left and right sides. There are separated transformers for
heating and anode (on both sides) using passive filtering.
To spare the tubes there is a two-phase anode voltage level control delay(GADAmpAn1).
The GAD 300 amplifier can also be supplied with 2A3 triode.
