Up for sale, Eico HF81 stereo integrated tube amplifier from around 1962. Restored and retubed this year. I have owned and worked on 5 of these amps so I know them pretty well.

Yes, they are as good as people say. Face, top, and knobs are clean and shiny.

Output transformers are great - sound is fantastic. Most parts and much of the circuit is original but has many new capacitors and resistors. Power switch moved to Tape switch at left - no longer need to adjust treble on every turn-on. Printed schematic and other printed info supplied.

Sounds great, warm and full, and reasonably quiet for a vintage tube amp. 2 Aux line inputs + very good refurbished Phono section.

Assortment of good tubes, US and Euro. 4 various, tested EL84 type tubes. Pairs matched by gm and current draw, not brand.

Hi-quality, mostly metal film resistors added. Cardas eutectic silver-bearing solder used in signal path.

4,8,16 ohm speaker terminals. Original screw-type speaker terminals with 4 gold-plated banana adapters.

Resistor added in power supply, brought down a too-high B+. New, long 2-prong power cord. You will hear popping sounds when turning Input selector switch, typical for vintage components. Despite the new power supply parts, there is a little background buzz/hum from old parts, such as pots and resistors.

You don't hear it from a few feet away. Original paint finish has a few markings. Knobs vary in color but they appear to be all as factory-supplied.

Chassis had a few small rust spots that were covered over. I rebuilt this amplifier to keep but I have other DIY amps as well. This item is in the category "Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps".

The seller is "denverartist15" and is located in this country: US. This item can be shipped to United States.
