Vintage Tube Amp

Offered for sale are the 3 tubes as titled and pictured. These particular 3 tubes tests strong and are closely balanced / matched. The tubes’ test results are displayed in the photos (New 5751 Spec 100% = 1,200 Gm). Note: Even though this tube is often considered interchangeable with the 12AX7, the 5751 does have a bit less gain than a 12AX7, so the test results displayed are the actual Amplitrex specs for the 5751. Also, these tubes are labeled Westinghouse, and there are no other EIA codes or numbers on them, but based on their construction style. And by comparison of hundreds (if not thousands) of other tubes over the years, they appear to be of Raytheon make / origin. So far, these boxes are still just a concept and in the prototype stage (3D Printed). Any and constructive feedback on the idea is welcomed and appreciated. Eventually I plan to offer these boxes for sale by. Themselves, but not quite yet. See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.

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.

This particular set tests very strong and are closely balanced. The print on these tubes is extremely fragile and will easily rub off, most has already rubbed off on one of them, special care was taken not to rub off any more while testing (the one that still has the most print is the stronger of the 2). The tubes’ test results are displayed in the photos (New 12AX7 Spec 100% = 1,600 Gm). See the photos for physical / cosmetic condition. Notes Regarding Tube Tests. All tubes are tested on an Amplitrex AT-1000 tester in the automatic Fixed Bias Mode (for the most conservative results). Test Results are for a general reference only, and are not a guarantee of performance, nor a guarantee of how they will test on your tester. No real world (audio) performance measurements are taken.
