Conrad Johnson PF-1 Preamplifier tubes and the tone controls areThis is a nice Conrad Johnson PF 1 FET Preamplifier. It is in very good condition with one scratch on the left side of the case. Please see the photos for details. All functions work properly and the phono section is very impressive. This preamplifier is built with high quality components and performs as new. I have used this preamplifier for a few months and I'm certain the next owner will love it. Thanks!! Bob
