EICO Model HF-12 AC 6 Tube Audio High Fidelity 12 Watt Amplifier Great looking 50+ years old unit. Local hobbyist/technician took it apart, replaced the plug, had it working but deemed it not for use due to case shock hazard. He noted items that need attention on the repair tag. It's missing one of the plastic button legs that it sits on. It's a tank---weighs over 11 lbs. Power output 12 watts into 8? Frequency response 25Hz to 20kHz.
Input sensitivity 5mV (MM), 500mV (line). Signal to noise ratio 60dB (MM), 75dB (line). Tube Complement 3 x 12AX7 (pre), 1x EZ81 (rectifier), 2 x EL84 (output). Dimensions 12"W x 3.75"H x 8.25D W. EICO left the audio market in the late 1970s and the electronics market some time later.
Two HF-12s may be used for stereo tape reproduction, each amplifier connecting directly to a tape head with no other electronic equipment required.
