Bottom Line:   
Wow!!! what can I say in stock form... just a really good cleaning of pots and sockets. ready for this... blows away my Mcintosh MC 240's, 40's, 275, and even betters my Marantz 8b and Mcintosh Mc 225. Ya it is that good. Timbre, detail, tone every aspect is just amazing!! all models were to spec.My Preamp was a restored Mx110z. This Eico is just outstanding. Paid $430.00. Was afraid to add caps but 6 were out of spec. Put Orange drops in her.( Now even sounds better.) Cant say enough about it. After years of searching. I'm Just done. Any Mac or Marantz will just be sold on line if I come across some. Always on the hunt. Just a side note .Leave as original as you can. Cheers!!!

Bottom Line:   
I am very pleased with the EICO HF 81. As someone who is new to tube technology this integrated amplifier was quite a surprise to my ears. I am a public school band director and a free lance musician. So when listening to any recording
the comparison made is "how close does the recording sound against when I am in the middle of a performance group or an audience?"

Originally, when I improperly hooked the HF 81 up 10 years ago the decision was to store it. A few months ago, after doing an internet search on and reading about the EICO HF 81, I hooked it up correctly......WOW! Woody Herman's Big Band had presence and warmth that were not there on my solid-state integrated amp. The 14 watts per side are more than enough to drive my Advent/2 speakers or Peavey PR12's (they are PA speakers with an 97 dB efficiency rating).

My listening diet is mainly small combo Jazz, Big Band, Polkas and anything that
shows group energy and clarity. This integrated amp makes it happen.

A major confession is that I repaced the original Mullard tubes in the HF 81. They had lived a long life and were going out of balance. So I repaced all of the pre-amp and amp tubes with JJ Tesla and the rectifier tubes with Electro -Harmonics. This added to better balance and warmth of sound. Before I did this I went through the HF 81 and cleaned the pots and checked the connections.

I whole heartedly encourage someone looking for a clean sounding, modest looking integrated amp to buy an EICO HF 81. I'm still amazed that an integrated amp that is as old as I am, sounds good !

I purchased an Eico HF-81 after reading the rave reviews on the net including this site. I have to agree with the majority that this little integrated has a beautiful sound - certainly much better than anything I have ever owned. I tried it initially with a pair of Burhoe Blue's that I bought in the mid 70's. While those speakers sounded great with the Leak TL50+ amp, they didn't quite make the grade with the Eico. I hooked up a pair of thrift shop $9.95 (Cdn.) B&W DM4's from the late 70's and voila! Lovely sound. Compact look.

The amp has all Mullard tubes. I know they are all strong but my experience with tube amplifiers and tuners is limited so have no point of reference to compare the tubes to any others. Suffice it to say the amplifier sounds better than anything I have ever owned. I am mostly a jazz listener with some classical and a dose of Santana, Steve Earle and John Lee Hooker. The base response is perfect for my ears. Not the chest rattling of the Burhoes hooked to the Leak put that accounts for very little of my listening these days and seems to offend some family members.

I am a garage sale and thrift shop addict. I ended up buying the Eico on ebay because I couldn't wait any longer. I figured the rest of my system cost me the equivalent of about $40 US in total (plus servicing where required) so the ebay purchase was affordable.

I am a fan of female singers. Patricia Barber is on as I type singing Norwegian Wood. Wayne Shorter was on before that. I am tickled pink with this amp/speaker combo and would recommend the amp to anyone. great sound at an affordable price. Mine was factory built, has original Mullard tubes. My tech replaced four resistors and did some minor adjustments and that was it.

My room is fairly large (350 sq. ft.) with hard surfaces.

This is a great amp. I use it with Accoustic Energy Aegis One speakers. Music sounds as if they are playing live. Incredible!! Poweful enough for midium size room. Zen amp and McIntosh MC-240 didn't sound any nearly good as Eico HF-81.

Bottom Line:   
A 42 year old integrated that uses cathode biased EL84's in a push-pull configuration operating in class A, then AB at higher volume, tube rectification, and a nice preamp/phono section. Listening to this amp, despite it's weaknesses, is pleasing, toneful and reproduces music with good depth. Good lay out of the controls, symmetrical in appearance and that brass faceplate is a nice touch with the brown enclosure. I recently finished rebuilding this amp with modern components and so it sings again, but without the hum and hiss. For those of you who already own this amp or just aquired one for modification go to this site-
