Vintage EICO HF-87 dual 35 watt vacuum tube power amplifier/amp with manual

Old mid-century vintage, Eico model HF-87 "High Fidelity Dual 35 Watt Power Amplifier", complete with the cage and original manual. This vintage stereo amplifier is rated at 117 VAC and uses 215 watts of electricity.  The manual has about 24 pages, including parts lists, schematics, diagrams and drawings. It has some pen and pencil marks. This amp measures about 15" x 11" x 7" over the protective cage.

We don't know much about this, but we've been told that the Eico HF-87 amp is considered by many audiophiles to be the best vacuum tube amplifier ever designed. This power amplifier is fresh out of an estate and is very clean. We plugged it in and the tubes glow, but we're selling this for restoration or parts.
