For those who like vinyl records this is the ultimate preamplifier for your record player. Standard configuration is for MM cartridges. Modification for MC is easy as all parts are through hole and only concerns resistors. As a power supply a separate transformer PCB (150616-2) can be used or a DC/DC converter module (PCB 150464-1). With the latter a standard 12 VDC/1 A AC adapter is needed.
