Product description:

This is a brand-new design work, referring to the NAIM original circuit 1:1 design concept, which reduces the internal flying line problem and better avoids the noise caused by the flying line. The whole machine is optimized to get adarker background and very quiet.

The power supply part is optimized, and the original NAC152 power supply rectifier board is directly merged into the preamplifier PCB, which reduces the additional power supply. It is more convenient to connect directly through thetransformer.

 

PCB size: 248mm*156mm

Input voltage: AC 24V--0--24V, AC 24V--0--24V (The minimum transformer power of each group is 25W)

(You can also use 1groupof 50W transformer voltage AC 24V--0--24V for power supply, but you need to short the K1 and K2 jumpers).

NOTE: This is a Bare PCB, and all parts need to be matched by yourself.
