About the HF22
The EICO HF-22 is a classic mono tube power amplifier manufactured by Electronic Instrument Co. Inc. of Brooklyn, circa 1959. It is widely regarded as one of the best sounding EICO amplifiers ever produced, incorporating a variation of the British Mullard 5-20 amplifier circuit with an Ultra-Linear output stage. 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.
