MOFI-12AX7/12AU7-Tube Buffer Pre-Amplifie-PCB

Printed Circuit Board Project 1、The PCBs sold in the store do not contain any components, and you should prepare them by yourself. 2、To complete this project, high level knowledge of electronics and rich experience in terms of soldering and testing are required. 3、Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve problems by yourself. 4、 We do not provide information other than the product introduction page. Schematic & key point of debugging PCB comes with component parameters for easy installation. We only refer the schematic of the amplification part of the circuit. If you need full circuit parameter, please read the component value with the PCB by yourself; we do not provide additionally. please keep test point voltage close enough to it, +-20% is also permitted. PCB SIZE:84X96X.16mm1oz Cu, HASLwith lead Gain: 1X Power requirements:Best:AC0-12V@1A
