Eastern Electric MiniMax BBA [Expired]


no longer for sale

This was purchased directly from Bill at Morningstar Audio as a demo unit - serial number 0760610 - in 2008. In addition to the the standard tubes, I also purchased, upon Bill's recommendation, 2 AWA 6BM8/ECL82 NOS Thorn Japanese tube and 1 Tung-sol 6X4 Big wavy D shaped getter tube. (Note- Photos in this ad are from the web.) I was originally going to use it as a tube buffer between my cd player and pre-pro in my home theater system. However, since it needs to be turned on and off manually, it wasn't user friendly enough for my family, although everyone did think it improved the sound. I then planned to use as an tube amplifier for an office system, but never got around to purchasing the other components. So, this unit has not seen much use since I purchased it. Now that I moved into a smaller place, I'm trying to sell various pieces of audio equipment, and decided that this one needs a new home. The EE BBA caused quite a stir when it was first introduced with several excellent professional reviews as well as much buzz on various forums. It has been described as the "The Universal Audio Interface that is the missing link in any chain of audio components". It is mainly designed so that owners can better match input and output impedances, differing input sensitivities, etc. between separate audio components in their systems. The BBA can be used to deliver an optimal electrical match between components. For example, it can be placed between a CD player, DAC, Tuner, or phono preamp and a preamplifier or receiver; or between a preamplifier and a power amplifier. It is designed to will work with audio components having input impedances ranging from 100k ohm to 600 ohm, and with input sensitivities from under 100mV up to 10V. The buffering circuitry uses two 6BM8/ECL82 combined triode/pentode and one 6X4/EZ90/U707 rectifier tube and has its own active volume control. Since it has only one input and output, some people have purchased several for use in multi-channel audio system. Specification • Maximum input: 6 V • Gain: 0dB to +18dB • Input Impedance: 220K ohm • Output Impedance: 800 ohms- 10K ohms • Signal to Noise: 95dB to 85dB • THD: 0.1% • Frequency Response: 10Hz - 100KHz • Power consumption: 35VA • Measurements: (W x H x D) 6.5 inches X 5 inches X 11.5 inches.
