See STK4231II and build a 2 channel OCL 100W stereo audio amplifier circuit with PCB layout. It's easy, small without adjusting, and cheap.
This 100W amplifier circuit by transistors, but very well OCL amplifier schematic.Use transistor MJ15003,MJ15004 as main. Power supply +38V 0 -38V 3A. [...]
Relatively easy to build up to 30W Amp OTL by TDA2030 transistor is packed into this project.the power dissipation of 20W at 8 ohm or 30W at load 4 ohm
Good transistor audio amplifier circuit, at 40 watts OCL RMS using 2N3055+MJ2955 is easy to build,and very inexpensive. To use Power Supply +35V -35V 2A.
This 50W OCL main amplifier circuit has high quality and economical,it is designed simple,easily created, electronics rookie.cheap when compared to other
The integrated amplifier that is smaller. For listening in a small room. Must have good the sound quality. Low noise and cheap.
This is 100 watts OTL amplifier circuit using transistor,For small PA system, in the village. The sound is very loud and very durable,easy to builds better [...]
