Eico HF 81 integrated tube amplifier EL84 US restored, upgraded vintage, stereo

  
Up for sale is my Eico HF81 integrated amplifier. Great sounding vintage tube amp, good bass.

I have owned and worked on 4 HF81s. Power supply capacitors changed (30uf film and F&T), along with other electrolytic caps and some important HV wires.

New coupling caps throughout - inc. Russian K40Y PIO and Solen. Voltages are a bit high but within spec. 6 tube sockets were replaced. Tubes are mostly US, including great GE oval plate 6BQ5s. The "Focus" (balance) pot was bypassed with resistors (commonly done with these amps).

Unnecessary amplifier separation switch on chassis removed from circuit. All original pots, clean and smooth. Has mostly older original parts and wires, but many new parts installed where needed.

Not butchered, drilled, or dented. Case was resprayed a few years ago. Knobs are clean but have been lightly glued on.

3 useable inputs - 2 line and phono. Line input jacks are new but phono jacks are original. The phono section is not the last word in vinyl playback but it's good.

Some noises heard in selector switch when turned to unused inputs (it's old). New speaker terminals, 4 and 8 ohm. Sounds like you hope it will - these amplifiers are legendary for a reason. It's a beauty- just polished the brass face plate.
