They are integrated(with preamp section) Mono(single channel) Power Amplifiers. NOS 60's vintage American made tubes. New CE can caps, new caps all around, and some new resistors that needed changed.New knobs as three were missing, so I took knobs from another amp and put 10 new matching ones on them. New bottom covers as these were missing. The previous owner drilled a pilot hole in the wrong spot in front panel for the pilot lights as seen in pics.
Thats about the only flaw on these. One is a slightly faded color than the other. Comes with a copy of the service manual. All the tubes have been closely matched for transconductance.These are excellent sounding amps. Tubes- 4 NOS vintage GE 6L6GB tubes, 4 NOS vintage GE and RCA 12AX7s, 4 NOS GE and Tung Sol 12AU7s, and 1 GE and one Nat. Each has its own bias control. One for each amp and one for the tubes. I believe these to be from the late 50's. Check out my other auctions. The item "Pair Eico HF-20 Integrated Mono Amplifiers Restored NOS Vint USA Tubes" is in sale since Saturday, January 5, 2019.
