Eico HF-81 Stereo Amplifier/PreAmp


Eico HF-81 Stereo Amplifier/PreAmp with manual. Much of the case is missing. Front panel is very good, markings are excellent. Original power cord is quite stiff. Chassis is dirty, no rust. Switch contacts very dirty. Initial test response was no output, cleaned switches, output on ch 1 but not on ch 2. After several cleanings and swapping tubes, same result. Injected a signal into input of preamp tube comparing ch 1 to ch 2. Both channels worked the same. Problem appears to be somewhere before the amplifier circuit, possibly still in the switch contacts. After an hour of testing the ch 2 transformer was 10 degrees warmer than Ch 1. Missing 1 knob. Sold as-is for parts or restoration. Approximate size 15.25"W, 11"D, 5"H. Item #10126
