Our entry level model, the (line-only) Manley Purist Preamplifier sets the pace with many of the features common to all our preamplifiers. This preamp is extra flexible in the gain control section. The "Volume" control attenuates the incoming signal level while the "GAIN" switch sets overall gain of the input stage by switching the first cathode resistor. But our favourite knobs are definitely the individual "Balance" controls which adjust the negative feedback. For more information about variable feedback, read "Notes on Negative Feedback".

We built this 24K Gold Plated Version for awhile...
