Congratulations on your purchase of the conrad-johnson model PV11
vacuum tube preamplifier. In it, you have acquired one of the finest
pieces of music reproduction equipment available today. It is the result
of more than a decade of research by conrad-johnson design into the
application of vacuum tube devices to the reproduction of recorded
music.
The PV11 was designed to provide audiophiles with a reference quality
preamplifier capable of accurately reproducing the dynamics, tonalities
and textures of a live musical performance. The design and materials
have been carefully selected to yield years of unvarying excellence.
The PV11 is available as a complete phono-preamplifier and control unit
or as the PV11L line stage preamplifier/control unit only.
Please take a few minutes to read this manual so that you will better
understand the features and capabilities of your PV11. NOTE THAT
THE PV11 LINE STAGE IS PHASE INVERTING. See the section
entitled "Getting the most from your PV11" for details on correct hookup
to your system.

- Page 4 The PV11 requires an ac power line providing between 108 and 125 volts at 50 to 60 Hz. Alternatively, the PV11 can be reconnected inter- nally for operation on 220 volt power lines. Consult your dealer for details about the conversion.
- Page 5 Output 1, Output 2: Connect this output to the input of your amplifier (or crossover in a bi-amped system). We recommend the use of an amplifier with an input impedance of 10k ohms or higher. Since the PV11 inverts phase, it may be necessary to invert the speaker leads to maintain correct phase.
- Page 6 Stereo-Normal stereo operation. Reverse-Passes the left channel input to right channel output and vice-versa. Mono-Passes the sum of left and right inputs to both channel outputs. This position produces a near mono signal at the record outputs. PV11 and PV11L Owner’s Manual...

Page 7: Vacuum Tube Replacement
VACUUM TUBE REPLACEMENT The audio circuit of the PV11 uses six vacuum tubes of three different types: two 12AX7 (V1 and V2), one 5751 (V3) and three 12AU7 (V4, V5 and V6). The PV11L uses two type 12AU7 (V5 and V6). Each type has been carefully chosen for its circuit application. - Page 8 PV11 Tube Complement V1 AND V2 type 12AX7 type 5751 V4 - V6 type 12AU7 NOTE: PV11L uses only tubes V5 and V6 PV11 and PV11L Owner’s Manual...

Page 9: Absolute Phase
This will be the case as long as the number of phase inversions is even (or zero). THE LINE STAGE OF THE PV11 INVERTS PHASE OF ALL INPUTS (including phono). If your system has an odd number of inversions, then you must add one phase inversion. - Page 10 Because the power cord on the PV11 is not polarized, it can be plugged in two ways. It will normally sound better in one orientation than in the other.
