Description
This listing is for a 210-Watt Electro Voice model 7100 reference power amplifier in perfect operating condition and good cosmetic condition. Please note that the rack handles are not included. This final version of the 7100 model was produced until 1998 and had a retail price of $500.00. It features a large toroidal core power transformer and two recently replaced 10,000uF/63Volt filter capacitors totaling 20,000uF, with B voltages of +- 61.0 Volts, at idle. The smaller electrolytic capacitors on the power supply have also been replaced. Large internal heat-sinking of the four, 130Watt, 180Volt 15Ampere TO-3P case output devices allow for safe operation into 4 Ohm loads with cool operation. There is a myriad of unobtrusive protection circuits to protect against any conceivable type of overload or unintentional misuse. These amplifiers are very reliable and reasonably difficult to damage. The circuit topology is quite respectable in its complication and thorough implementation. The front panel a power switch, level controls for each channel and two highly accurate LED clipping indicators. The rear panel has four 5-way binding post speaker terminals, two recently added RCA line-in jacks, two XLR line-in phone jacks, and 4 Ampere power line fuse. The unit measures 19W x 9D x 3.75H and weighs 23lb when packaged. Into 8? non-inductive test loads, better than 106.6 Watts per channel are available from 20Hz to beyond 30kHz, with both channels driven. Into 4? loads better than 134.4 Watts per channel are available from 20Hz to just under 30kHz. The power output ratings are obviously quite conservative. The quiescent DC bias is +-1.5mV. The offset averages a very stable 2.5 to 3.0mV at warm idle. This is the last of six similar units I purchased within the last year. I am only selling them to make room for other audio treasures. They make excellent medium power amplifiers for use in home audio applications and will stand comparison with the best solid-state designs for sound quality, durability and especially quality of build. Please Note: The addition of RCA input jacks is a modification intended to facilitate more convenient use with home audio applications. Therefore, the end user has a choice of either RCA jacks, or XLR jacks for inputs.
