Classic Valve Design
PB Preamp

The PB Linestage was developed at the request of a client who desired a little extra control over his music.

Sometimes music sources aren't exactly calibrated for an industry standard output for a given input or other reference. Sometimes this value can be much higher or lower. This linestage was built with the idea that as well as a level control, a switch could be flipped to change the overall linestage gain. Stock values are +3 and +6dB. You may specify up to +13dB for the high value.

For best hum and noise performance, this linestage features a vacuum tube regulated power supply with accurate 5651 reference tube as the regulation reference source. Vacuum rectifier assures slower application of high voltage for maximum tube life.

In order to accomodate the equally good performing, but less expensive 12SN7GT tubes, the linestage comes with switch selectable 6V or 12V heater power.

These are production units. Model shown would use an Edcor power transformer, modern chassis 2 year limited warranty for $900 USD.

We cannot ship these to Europe or RoHS compliant countries (lead based solder joints).
