The frequency of this circuit depends on the crystal. The transistor supports a modern equivalent. We found it in documentation from the 1980s.
This circuit provides 70 W at 8 ohms and 100 W at 4 ohms. We found this amplifier in a 1992...
This circuit was obtained in a 1989 publication and is quite simple to assemble, but critical in...
This amplifier with a few watts of power was found in a Japanese technical documentation from the...
