Switches and  Controls - 

The Rogue Ninety-Nine is equipped 

with the following controls  

 

Volume - gain adjustment from 0- 23 dB 

 

Gain - a variable gain adjustment for source and speaker matching. 

 

Source - selects source material (CD, phono, tape, tuner, aux) 

 

Power - on/off operation 

 

Mute - leaves preamplifier on while muting output 

 

Mono - combines left and right channels. 

 

Record - must be pressed in while taping, isolates tape player when not 
in use. 

Note  - 

Unlike many solid state amplifiers, the 

Ninety-Nine preamplifier should not be left turned 
on when not  in use. To prolong tube life, turn off the 
unit when not in use.

Remote Volume Control - 

The Rogue Ninety-Nine is equipped 

with an analog remote volume control feature. The volume may 
be adjusted manually using the knob on the front panel, or by 
using the remote control provided.   

Note  - 

Some noise may be heard when operating the 

remote volume.  This is normal and is a result of the 
DC motor noise being picked up by the sensitive 
audio circuitry during the volume change.  

 

 

Note: This unit will not play for approximately 20 
seconds after power on while tubes warm up.  

up.  12AX7 tubes can also be used for even greater gain.  It should 
be noted however that very low noise tubes must be used in the first 
gain stage (the two rear 12AX7 tubes) so that tube noise or “rush” is 
kept to a minimum.   

3)

 

The cartridge loading is factory set for 47K ohms and 150pF of 
capacitance.  This is suitable for most moving magnet and 
moving coil cartridges.  Special cartridge loading can be ordered 
from the factory or from your local dealer. 

4)

 

Connecting the power supply - 

Carefully plug the connectors, 

Con A and Con B, coming from the power supply into the rear of 
the preamplifier.  See Figure 2.  Connect the IEC end of power 
cord to the power supply, and plug opposite end into 
corresponding outlet. 

Note: Be careful to ensure 3 and 6 pin sockets (Con 
A and Con B respectively) mate to corresponding 
plugs. See Figure 2.
