Miller's Minimal Preamplifier

Built for Rod Miller

Miller's Minimal Preamplifier came out of the need for a very simple preamplifier for Rod's nice tube Fisher integrated amplifier.  The original preamplifier (and especially the phono preamplifier!) left something to be desired so we decided to bypass these via the convenient jacks Fisher provided.
The switch on the front switches between the active opamp-based phono preamplifier and the passive input for a CD or other source.  The power supply is external for less interference.
