MAKE SURE THAT THE BIAS SWITCH IS SET CORRECTLY TO MATCH THE TUBE TYPE THAT
YOU ARE USING. Failure to do this will result in tube failure that could possibly burn resistors in the Bias supply. Although
this is a fairly simple repair for an authorized technician, it is easily avoidable. ALWAYS CHECK THE BIAS SWITCH setting if
you experiment with alternate tube types and you will enjoy uninterrupted performances from your amplifier.
TUBE TRACKING / DIODE:
This patented switchable feature allows you to select between two different types of rectifiers for
different sounds and feel. It first appeared on the Dual Rectifier Head and is, in fact, part of the magic behind the whole Dual Rectifier
series of amplifiers. It has since found its way into some of our other products as well, such as the Maverick,
Heartbreaker and the Blue Angel.
The Dual and Triple feature Channel Specific RECTIFIER SELECT switches that allow you to match the Recti-
fier style to the power output and preamp selections you have made to further enhance the performance of
the footswitchable sounds. The two choices each have their sonic benefits and stylistic leanings. They create
nuance and flavor that will put the Channels in iconic territory right away. By setting the Channels with differ-
ent Rectifier choices - when appropriate - you will also increase their differences and showcase the amplifiers
incredible versatility.
DIODE: (Hi Power) calls up the silicone diode rectifiers which offer more punch, a tighter attack with added brightness and substan-
tially more headroom. This would be the preferred position for loud clean playing or tight rhythmic playing with a high front end GAIN
setting. When you want the low end to track tight.
TUBE TRACKING: (Normal) This position takes a power section walk down memory lane, paying tribute to those vintage gems of
yesteryear. In those early days of amplification, the only rectifiers available were tubes. Unbeknownst to their creators, these sweet
sounding amplifiers would someday become relics as the demand for higher volumes and more power per package led to the abandon-
ment of the tube rectifier in favor of the five cent silicone diode’s greater efficiency. With this decision went much of the sweetness and
soul, and by the late 60’s, most amps were bold, loud, and efficient, and unfortunately...sometimes lacking some of that earlier soul.
We wanted the Dual Rectifier series to capture that... “thing” that you... “can’t quite put your finger on...but you know it when it’s got
it.” Soul, Personality and Feel. The VACUUM TUBE position gives you a sweetness of sound and a liquid feel that simply cannot be
duplicated in any other way. This position shines for single note lead work in Channels 2 and 3 and delivers a warm, breathing sound
in the RAW and VINTAGE modes that was previously unavailable in all but the best vintage amps.
This switch calls up the proper amount of tube rectification (number of tubes) for a given output power setting determined by the Front
Panel POWER SELECT switch found in each of the three Channels. In the 50 WATT setting one 5U4 is brought on line producing
the saggiest, most clippable power mode. In the 100 WATT selection, two 5U4 are activated ( all three 5U4 are activated in the 150
WATT mode of the TRIPLE RECTIFIER) and a higher output “vintage inspired” power voice is revealed. This setting is great for sweet,
bouncy clean work, thick hazy crunch rhythm and soulful liquid lead sounds.
