POWER RATING:With 63V supply capacitors the supply should be limited to about 60V, and then the amplifier can produce about 30W into 8ohms and 50W into 4ohms. High voltage output and driver transistors (160V) are used, and although not recommended, the power rating can be increased just by changing the supply voltage and using capacitors with adequate voltage …

The power output is determined by the load impedance and the available voltage and current of the amplifier. An amplifier that is capable of a maximum of 2A output current will be unable to provide more just because you want it to. Such an amp will be limited to 16W 'RMS' into 8 ohms, regardless of the supply voltage.

Smallest Two Transistor Design. This simple two transistor class A amplifier circuit works by using Tr1 as a common emitter driver stage configured to directly operate Tr2; the common source output stage. R1 to R3 are positioned to bias the circuit to ensure that we have a quiescent current of approximately 25mA by means of LS1 and Tr2.

The original amplifier design was for a 30W amplifier with a 60V power-rail, and because of the purity, this is more than adequate for normal home use. In 1971, 100V small-signal transistors were rare, but this is no longer so and an 80V power-rail can now be used, with different transistors, increasing the power to 50W.
