Here is what the manual has to say about the "Recto-Tracking."
This seems like total BS to me. I'm going to be really bummed if I can't get 100 watts of Tube Rectification.
RECTIFIER SELECT with TUBE-TRACKING: This two position toggle selects the type of rectifi er, Silicon Diodes or Tube, which
converts the voltage from AC to DC for the power supply. The Roadster
incorporates a further improved version of our patented Switchable Rectifi er feature fi rst seen on the Dual and Triple Rectifi er SOLO heads. It incorporates a Rectifi er Tracking™ feature that
insures proper voltage is present at all times and improves reliability. This switch operates in tandem with the individual Channel
Power Select (50/100) switch located in each Channel Strip.
The Rectifi er Tracking feature monitors the Channels, determines their power status and automatically selects the proper rectifi er
type - which ultimately assures the best sound. This provides optimization of the power settings, delivering a magical tube-rectifi ed
power-sag vibe for the channel set to 50 watts - and a tighter, bolder 100 watts of diode-rectifi ed authority for the channel set to full
power. Here is an explanation of how the two choices work;
DIODE: Calls up the silicon diode rectifi er, which offers more punch, a tighter attack with more brightness and substantially more
headroom. This rectifi er choice provides the highest power and therefor the tightest rectifi cation. This setting would be best for any
application where maximum headroom is needed or tight bass response is called for. Situations that usually require this are clean
rhythm playing or extreme high gain crunch rhythm sounds.
RECTO TUBE-TRACKING: Engages the 5U4 rectifi er tube automatically whenever the 50 watt selection is made via a Channel
Power Select switch. When switching channels - if the Channel Power Select is set to 100 watts, the Diodes are automatically
engaged to insure proper matching to the added load on the supply. This innovative feature allows you to tune each channel for the
ultimate power expression and feel.
