***************************************************************************
The Reveille Vacuum Tube Linestage is our version of a cost-no-object preamplifier. Granted we could have gone further and gold plated many more items and incorporated the use of even more expensive parts, we chose once again to error on the side of sanity and produce a well engineered, top quality product we hope will be affordable for many of you.
The pre-amplification circuit is simple, keeping with our minimalist approach, and consists of a single stage SRPP using the 6SN7 octal base triode tube. The 6SN7, known for its low distortion, provides a very neutral sound while maintaining the natural harmonic integrity of the music signal. The Reveille linestage incorporates the use of a very high quality input transformer for decoupling the preamp from noise generated by source equipment. This feature reduces the overall noise floor resulting in greater resolution, added dimensionality and a grainless treble. The input transformer also inverts the phase which in conjunction with the SRPP circuit results in a non-inverted output signal. The pre-amplification stage is dual mono.
The Reveille Linestage uses the best quality passive components available such as Caddock resistors and capacitors from Solen, Elna and Hovland MusiCaps. Oxygen free copper hookup wire is used for the interconnections along with the well known Cardas silver rhodium rca connectors for the inputs and outputs. A super high quality 24-position, ladder-type stepped attenuator using 1% metal film resistors controls the gain and input selection is accomplished via silver contact toggle switches. And finally, the circuit board is a solder plated 2 oz. copper double-sided board that is solder masked, silk screened and incorporates the use of a ground plane for emi/emc shielding.
The power supply design is also dual mono except for the detachable power cord. It features two toroidal power transformers along with a separate on-off switch for each channel. The power supply uses the ultra fast rectifier diodes for reduced noise and a mosfet regulator stage for each channel provides a very stiff voltage source for the preamplifier circuit. Ripple voltage is less than .001%. The filament voltages are also regulated and biased for reliable SRPP operation.
The all aluminum chassis are identical in size and measure 2.25"h x 14"w x 10"d. The chassis front and rear panels are 3/8" aluminum, bottom panels are .09" and the top panel of the preamplifier is 3/8". The side panels are cnc machined out of 1" thick aluminum and styled to match the shape of the front panel. This design makes for a very rigid, solid and heavy chassis. A nice feature of the linestage is its slimtyling while still allowing for the tubes to be visible and accessible without having to remove the top cover. The front panels are clear anodized aluminum as pictured in the photo. The remainder of the chassis is powder coated with a black textured finish.
The linestage includes: 4-input capability (CD, Tuner, Aux/Phono, Tape), 1 main output and a tape out for monitoring. The power supply chassis and preamp chassis are connected via a short umbilical with a connector on each end.
