In addition to the Pre 1P, its covers, and the operating
manual you are presently reading (with associated inserts
and warranty card), there are a few more items to take
inventory of before steps are taken to make the Anthem
Pre 1P operational.
These items are:
• one each selected pair of 6922/6DJ8 and
12AT7/ECC81 tubes totaling 4*.
• a glove for handling the tubes
• a detachable AC power cord
• 18 screws
• 1 Philips #1 screwdriver
After completing an inventory of these items, proceed
to the next steps.
*These tubes are carefully measured and matched in
pairs. Take extra care to keep the pairs from being mixed
and mismatched which would degrade performance.

A PR EAMPLIFIER L ED
This Light Emitting Diode illuminates when power is
applied and the Pre 1P is turned on via the ON-OFF
Button (B)
B ON-OFF BUTTON
When in the ON position (button depressed), all power
supplies within the preamplifier are initiated. A delay of
approximately 45 seconds is required for the power
supplies to stabilize. After the 45 second delay, the
muting relay will engage, and the phono stage is
operational. When in the OFF position (not depressed),
the Pre 1P is OFF.
