Recommended at 30–120mA for optimal thermal stability and sound quality.

Typically 100W to 300W depending on the number of output transistor pairs and supply voltage.

It features a symmetrical differential input stage, a voltage amplification stage (VAS), and a powerful output stage usually based on Toshiba 2SA1943 and 2SC5200 transistors.

The output transistors must be mounted on a significant heatsink. Using mica insulators and thermal paste is essential.

For the best performance and to avoid one side "pulling" more current, matching the gain of the output transistors is highly recommended.

The quiescent current must be adjusted on a "warm" amplifier. It is crucial to let the radiator reach operating temperature before final tuning.
