Previous Owner’s original notes on this amplifier: ALTEC LANSING QUAD INPUT PREAMP/AMPLIFIER RATED 35WATTS. POWER ON AND WORKING OK, BUT ONE NEEDS NEW CAPS SOMEWHERE, BECAUSE I CAN HEAR A HUM. [INPUTS] HAVE RESISTIVE NETWORKS INSIDE THE CANS, THUS MUST BE ALL HIGH IMPEDANCE INPUTS. Previously used condition with some scuffs, scratches, grime. Green covering on wood cabinet is deteriorating. Wood cabinet is rickety. Powered on – all tubes glow. Unit was tested by the previous owner who states it must need a new capacitor, because there is a hum. Power cord has old replacement plug – we recommend it be inspected and possibly replace with something more permanent. The GE 44 bulb in the power on indicator is burnt out. This is an item from a huge collection of vintage ham radio, test equipment, parts and camera equipment we are currently processing. We have many manuals, Ham Radios, thousands of test equipment and associated parts and pieces. The previous owner was a Ham Radio operator who collected all of these interesting items over the years. He really focused on purchasing equipment from special surplus auctions at the Nevada Test Site, Sandia Labs, Nellis Air Force Base, Kirtland Air force Base, etc. Many of the items we have are from EG&G, Department of Energy, NASA, Air Force, Navy, Marines and Army. The previous owner kept notes on nearly everything as it seemed to be his life-long hobby to collect, test, and document everything he owned. Manufacturing technology was not the same as it is today so imperfections should be expected. Also, these items may have been in storage for 40-80 years and could be dusty, greasy or have surface rust, spider webs, etc.

The empty octal socket on the chassis is likely for a plug-in type transformer. Further research and reverse engineering of the wiring may help yield a better idea of what this unit was used for. There is wear from use/storage like scratches, scuffs and dust. Comes with one Jones plug and tubes. 2 x General Electric 12AX7. 1 x RCA 6AQ5. 1 x General Electric 6X4.
