Vintage Tube Amp

This a Great estate sale find, it is an EICO HF20 Monoblock Audio Amplifier. It is in Excellent working condition, with two 12AX7 preamp tubes. This amplifier has been in storage for fourteen years. It belonged to the owner of a high end audio transformer company. It is a kit build, very cleanly done, but the storage had taken its toll. All of the tubes were gone and I’ve replaced them. I have not cleaned the rust or corrosion off of the amplifier, that’s up to you to do and you can do as much or as little as you desire. What we’re talking about there is cosmetics, this amp it sounds great; all of the pots and switches have been cleaned, and the voltages checked. The amplifier is an Ultra-Linear Williamson type, with a 20 watt output. The preamplifier/equalization section uses inverse feedback allowing it to match the low distortion of the power amplifier. Bass and Treble EQ is ±15db. It has outputs for 4, 8, and 16? , plus a Tape Recorder output. There are seven inputs, two Phono with Equalization, Tuner and four high level jacks. The amp weighs 24 lbs. A copy of the manual and assembly instructions is included. I played it for six hours; it had no glitches, no smoke and a wonderful sound. If you need more pictures or information please let me know.

Here’s a vintage set of RCA 7591a tubes. The tubes look to be in great condition. I don’t have an official tube tester but I tested them in an amp and they seem to work and sound as a good set would should.
