The Eico has been listed on Ebay.. Bid soon as the auction ends in a few days


Here we have a fairly rare and really clean Eico HF-85 that has undergone a basic restore. These are highly regarded and the Eico HF85 sounds great. This fine example can be yours for $1100.00

This preamp is running 5 12ax7 tubes, and you will get the following tubes with your preamp: a 1250 reading is new test
2 Eico branded Mullards 1100/1250 – 1125/1250 and 1100/1250 – 1050/1250
a matched pair of Amperex Bugle Boys that test 1400/1250 – 1400/1250 and 1425/1250 – 1400/1250
and a single NOS Sylvania 1450/1250 and 1400/1250.

The Amperex Bugle Boys test as new however I do not have the boxes, the Sylvania is genuine NOS.
The 6X4 Rectifier is an Eico branded mullard

Electronics: 9.5 out of 10
This preamp has had all of the electrolytic caps replaced along with all of the coupling caps. A 3 prong grounded cord has been installed and the tubes have been tested and replaced. All of the pots have been cleaned with de-ox and now operate scratch free and quietly. The power switch was worn and has been replaced with a new reproduction switch.

Cosmetics: 8 out of 10
The overall condition is 8.5 out of 10, the chassis has been cleaned and the brass faceplate has been polished to a high shine. The knobs have been cleaned and polished and are all original. The paint has been buffed and waxed with automotive wax. There is some slight corrosion on the right side panel that has left some slight pitting on the paint. The top vented gold panel has a few small areas where the paint has been slightly discolored and worn and on the thin side. The rear panel and RCA jacks are clean and have been sprayed with contact cleaner. The phenolic backing plates for the RCA jacks has deformed slightly over the years (this is common for these types of jacks) The interior chassis is clean and most of the dust and grime has been cleaned off, with the exception of the area directly under the pots. All of the screws are original and clean.
The preamp looks great and is clean and presents well.

Recommended mods:

  1. Remove the hum pot and convert the heaters to DC – this will make the pre-amp run more quiet (improved S/N)
