The EICO HF-22 is a classic mono tube power amplifier manufactured by Electronic Instrument Co. Inc. of Brooklyn, circa 1959.

The amplifier features a metal chassis design and includes a power supply suitable for preamp applications. It requires external speakers and is designed as a chassis-only unit suitable for building into custom enclosures. The HF-22 has become a sought-after vintage amplifier among tube audio enthusiasts for its warm, sweet-sounding characteristics.
