The LaChapell Audio Model 992EG is a two channel fully balanced all-tube preamplifier and instrument input amplifier.
Meticulously hand assembled, every aspect of the 992EG speaks of our dedication to quality of sound and solid, robust construction. Utilizing a total of eight vacuum tubes promises that the 992EG will absolutely awaken your ears with its warm melodic character and rich low-end response. But, what makes the 992EG such a powerful preamp is the level of control the user has over both the input and output stages. Allowing the user to actually throttle gain in or out of either the input stage (for loads of character) or the output stage (for a more clear, transparent response) by way of fully variable potentiometers secures the 992EG as one of the most flexible vacuum tube preamps available in today's market. For the 992EG's input stage we chose one of Jensen's best microphone input transformers; the JT-115k. along with two 12AX7/ ECC83 vacuum tubes per channel; allowing a generous >74dB of raw internal gain. With over 40dB of gain deployed to the input pot alone, your ability to drive and explore the sonic potential of this amplifier becomes very dramatic. The harder you push the input stage the more harmonics are generated; even into 15~20% distortion! And, since this is a balanced amplifier (meaning both negative and positive rails are amplified internally) the distortion will sound compressed and full of energy. The direct instrument input (Hi-Z) stage on the 992EG utilizes the high performance Cinemag CM-DBX direct transformer which feeds the balanced differential amplifier input. This double balanced approach allows for an extremely quiet Hi-Z stage; renowned for it's rich, clear, full sound- highly favored among electric guitar and bass players. The 992EG's output stage features a cross-coupled push-pull topology which includes two 12AU7 tubes in parallel with the Jensen JT-11BM line output transformer to balance the outputs.

I bought the LaChappell 992 EG and was really not too excited about buying it, but I did buy it. Little did I know what was yet to come. I had it for a few days and finally got a chance to try it out. I ran a Lewitt LCT 940 in Fet mode. I hooked it up to my LaChapell stood in front of the mic and started to strum a few chords.

I was not at all ready for what came back into my head phones. The more I played the more I was astounded with what I was hearing. It was so natural and so if I wanted in your face. . It is a well thought out mic pre. Love the channel mute. Love you have total control over the input and out put which makes a huge difference in sound. I was very very impressed. Saturday and Sunday I was recording in my studio and used this combination and added the AEA R84 for vocals on both days. Both days I got compliments on how good the combination sounded. All weekend long all my other mic pres were turned off and the LaChapell did everything I needed and the sound was bar none, the utmost best I had ...So if you are thinking about buying this mic pre, stop thinking and buy it. This mic pre has found a home and will never ever be not in my studio, it is that good.
