2PCS 300W L10 Amplifier Board Power Amp Board Class AB 2.0 Channel for 4-12 Inch speakers DIY
Description:
Referring to the design of L10 circuit, the boards use 1.6mm double-sided PCB and 5-ring high-precision resistors. Some small capacitors adopt Tianhe hifi capacitors, and new original transistors (TT1943 and TT5200) for Toshiba are used. 6pcs transistors (with excellent control) per channel for excitation are C5171 and A1930 audio transistors. Due to reasonable circuit design, no current sound of the whole machine will be generated, with pure sound quality and outstanding details. Class A performance enables warm and smooth sound, outperforming the sound of tube amplifiers. It is cos-effective and your choice for DIY. It is suitable for 4-12 inch speakers.
There are two power amplifier boards for two channels (one amplifier board for one channel). All the boards have been debugged. To make a finished power amplifier machine, heat sinks, power supply rectifiers, transformers, shell, etc. are required.
Basic Parameters:
- Amplifier board size: 200 x 68 x 30mm/7.9 x 2.7 x 1.2" (LxWxH)
- Class AB output power: 300W at 4Ω; 200W at 8Ω
- Recommended input voltage: plus or minus 28V-45V DC input
- Recommended transformer parameters: dual AC 24-35V output, over 300W
Package Included:
- 2 x Amplifier Boards
Note:
- The boards are assembled and ready to use.
- The default quiescent current is set to 300MA.
- Due to component sourcing, the details pictured are not guaranteed to be exactly the same as those of the actual products. Pictures are for reference only. Please make sure that you don't mind before purchasing.
