Integrated Tube Amplifier
Single-ended
Class-A
Dual Mono

First is an amplifier of Audio Reveal brand – a company that produces high-class tube audio equipment. Our philosophy is to create audio equipment, which provide neutral and musical sound, which is authentic. „Reveal” means „discover” – it is the essence of Audio Reveal amplifiers sound..

“First” allows you to discover music again in a new perspective; the amplifier was created with passion for a good sound.

Single-Ended Dual Mono circuit produces true tube sound, also positively influencing amplifier parameters. Using two tubes (12AX7 and 12AU7) in the preamplifier section give more precision in the sound. Beam power tetrode KT88 working in the SE circuit allowed to obtain 10W RMS power.

The amplifier is equipped with an initial warm-up system, which extends tubes lifetime. Furthermore, “first” has a protection against overheating.

An additional feature is an NFB (Negative Feedback) switch, which allows you to adjust the sound to your preferences.
