"Parabee is short for parallel feed 300B. This is the kit that everyone has been asking for, a higher powered SE amp using technology similar to our popular 2.5W Paraglow parafeed 2A3 kit. We threw everything we have into this one.Parabee uses an improved version of the driver design of our B-Glow 300B kit. Half of a Svetlana 6N1P as the input/driver stage. The 6N1P is loaded with our Camille Cascode Constant Current Source for super quiet, dynamic, linear performance. The single driver stage is RC coupled to the grid of the single ended 300B, which runs on AC filaments using the elegant hum reduction circuitry designed by Steve Bench. The operating points for the amplifier were specified for maximum linearity by VALVE's technical editor, Paul Joppa, and of course it uses Mike LaFevre's superb MagneQuest transformers throughout.
The power transformer is our versatile, quiet PGP 8.1, made for us exclusively by MagneQuest, and the filter choke is the new MagneQuest RGC-6, the only filter choke made that uses a special non-magnetic channel frame material for optimal magnetic performance.
Rectification is by low impedance ultrafast rectifiers with a special filter that lets the amp match the sweet sound of tube rectified amps in the midrange and top end while showing vastly superior bass performance. Filter capacitors are the excellent Panasonic TSHB series.
The C4S active load assures that the 6N1P driver is dead quiet, and running in as linear and dynamic a fashion as possible. The stages are coupled with Vishay/Dale metal film resistors and Solen polypropylene capacitors.
The super linear 300B gives the power necessary for those of us with great sounding, but less-than-horn-efficient dynamic loudspeakers, a clean 8 watts. And they are also marvelous with horns, giving you bass response you may not have heard before. We offer the kit for $1499 for a pair of monoblocks without 300Bs so that the builder may chose their favorite brand, and we also offer the superb TJ meshplate 300Bs for an additional $275 the pair.
The parallel feed output stage uses the MagneQuest EXO-03 plate loading choke and the all nickel TFA-2004 parafeed output transformer. Brass bell ends are supplied on the TFA-2004, and are now available exclusively to Parabee owners.
The amp also comes with a new, deeper oak base, and we include our radical, fabulous sounding braided solid wire core power cord in kit form."
I love these amps, but I just have too many toys. Note that these have custom natural oak bases that are routered to allow for easy access and removal of the amps for upgrades or tweaking.
Amps will ship with a matched pair TJ 300B mesh plate tubes along with Svetlana 6N1Ps.
