Amplifier PCB for TDA2030/LM1875
Convenient PCB for dual-channel, stereo operation for TDA2030 or LM1875 single chip amplifiers. Great for making a complete low-cost amplifier based on either of these chips. This board can be used for dual channel - commonly referred to as OCL (do not install R5) or for BTL (Bridge-Tied Load). For BTL, install R5 (22K), short the right input and connect the speaker across the two speaker outputs.
