Little 3w x 3w PAM8046 amplifier and Aiyima pre amplifier (Hillsborough S6)

Aiyima is a little tube buffer pre amplifier, runs on 12v DC supply which I no longer have. Its not an amplifier in itself but more of a buffer between source and main amplifier to add "tube like" harmonic distortion. If you know you know. The other is a little amplifier board that can be wired directly to speakers and use the 3.5mm input for a source such as CD, phone, mp3 etc. Has a USB cable already wired in and just needs a phone charger adapter to use it
