Fantastic tube preamp from the 1950s. My favorite preamp Ive ever used. This has been modified for modern use. This is a single ended preamp that was originally 90 dB of gain. A tube stage was taken out of it to knock it down to 70db of gain. I only sell in the USA. The item "Gates Biamote Tube Mic Preamp" is in sale since Saturday, December 1, 2018.
