SLP-2002 USERS MANUAL
SLP-2002 Design Features: The headphone jack is driven by the buffer stage 5814 tubes
through specially chosen audio grade transformers. These audio grade transformers were
included so that the sound quality of the SLP-2002 would be preserved and offered to
headphone lovers. Headphones may be used with or without having the power amplifier and
speakers turned on. If you have very efficient speakers and inefficient headphones, it may be
necessary to turn off the power amp to avoid excessive ‘in room’ loudness. The 6922 driver
tubes are direct coupled to the 5814 buffer stage tubes for the best sound and drive capability in
this preamplifier. With the 5814 tubes driving the headphone transformers, the result is a
glorious sounding headphone driver circuit.
The SLP-2002 power supply has five fully regulated stages for the B+, the tube filaments and the
control systems related to the volume control. The volume control is a four-gang ALPS
potentiometer. This four-gang design is needed due to the truly balanced design of the four line
stages in the preamplifier.
The Remote Control Handset: Please insert the AAA batteries into the handset, aligning
the positive and negative terminals to ensure the remote control functions properly. The
handset flashes a small red LED to confirm it is working. If you push a button and the red LED is
not flashing it indicates that the batteries are depleted. Change to new batteries and your
remote control will work again. The remote control handset has Volume control Up or
Down and muting On or Off.
If you engage the mute circuit the SLP-2002 output circuit is muted. However, the
remote handset will still operate the volume control circuit. Please be
careful not to turn up the volume to a high level and then turn the mute off on the SLP-
2002. The subsequent high volume level signal might startle you or possibly damage your
speakers if it is set at too loud a level.
