I have several projects on the bench, but today I'm starting work on a new version of the 1401 Stereo Mic Amp. I did some prototyping first and the new version will have a lot of really impressive things to offer. First off, some changes were made to the amplifier design that allowed me to coax 5 more dB of gain out of the amp. The only trade off is a slightly warmer sound. Win+Win! Also, a new feature is getting added to the preamp. Based on user feedback, there is now going to be a mic/line input switch on both channels. Another new feature is the treble control bypass, which is incorporated into the treble knob itself. A switch is built into the knob... turn it down all the way and then a little more until it clicks. Bypassing the treble control will allow for a couple more dB of gain and a gentle touch of brightness. Finally, it of course will incorporate the new LBA noiseless DRDR tube power supply.
New stats (based on prototype):
Noise Floor: -86dB
Gain: +45dB per channel or +47dB with treble bypassed.
Actual stats will be presented on the 1401 Preamp's product page after the completion of this first production version of Revision A.
