The Ampapa A1 is a phono preamplifier specially designed for compatibility with MM cells, based on the use of two JAN5654 tubes for a warm, vintage sound, no less clear and precise. Added to this are 3 potentiometers for tone and volume control, allowing you to adapt the sound reproduction to your individual tastes. As an attractive touch, green or red LEDs illuminate the tubes and the perimeter of the unit. On the connectivity side, you'll find a phono input, as well as an RCA input and a 3.5mm headphone output in addition to the RCA output. The aesthetic uniqueness and versatility of this little phono preamplifier will delight many a music lover.
