RedPlate Twe Operations Guide
4
TWEED
– Same as rotating the Mode switch to position 6, for a traditional fat tweed tone. The
footswitch button has no effect if you are already on position 6 of the MODE switch on the front
panel because it is a duplicate function.
BOOST
– Girth Boost feature which adds volume and tone by doing a full tone lift. The
footswitch button has no effect when the front panel Tone control is rotated to zero because it is a
duplicate function.
POWER ON/OFF PROCEDURE
1. Check the front panel Standby switch to make sure it is toggled downward for Standby
operation (the Standby switch is located at the right side of the front panel next to the pilot
light).
2. Toggle the main power switch to the up position (this switch is located at the right side of
the IEC input module). The front panel pilot light should be lit.
3. Wait one minute and then toggle the front panel Standby switch upwards to the Operate
position.
4. POWER OFF
– Toggle the main power switch downward, there is no need to go into
standby first although it will not hurt anything.
MAINTENANCE SECTION
Your Twe amp has been designed for years of trouble free operation. The vacuum
tubes will need to be replaced over time. We recommend new output tubes every 160 - 240 hours
and new preamp tubes every 320 - 480 hours.
The front and rear panels have a protective finish that can be easily scratched with abrasives
so always use a damp soft cloth to clean them (never use paper towels).
TUBE CHART
All tube brands are acceptable, a long plate is preferred in the V4 (Phase Inverter) position.
Warning
– No user serviceable parts inside so unless you know what you’re
doing please refer to a qualified service person only.
BIAS PROCEDURE
1. When new 6L6 GC output tubes are installed it is important to re-bias the amp for optimal
performance. No biasing needed for 6V6 tubes because they can only be used in cathode
bias position.
2. ALWAYS HAVE A SPEAKER CONNECTED.
3. Use a digital volt meter set to DC volts at lowest scale (MV). Makes sure the black lead is
the common terminal of the meter and the read lead is the DC voltage terminal of the
meter.
