RedPlate RP50R Operations Guide
1. Check the Standby switch to make sure it is toggled downward for Standby operation.
2. Toggle the main power switch to the up position (this switch is located at the top of the IEC
input module). The front panel pilot light should be lit.
3. Wait one minute and then toggle the 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.
Your RP50R 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 control 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). The cabinetry
can be cleaned with our super secret tolex cleaner (on a paper towel - 2 squirts of WD-40 and 4
squirts window cleaner), do not spray on the control panels.
All tube brands are acceptable; a long plate is preferred in the Phase Inverter position.
CAUTION - NEVER MIX 6L6 AND 6V6 TUBES AND ALWAYS HAVE A SPEAKER
CONNECTED.
Warning – No user serviceable parts inside so unless you know what you're
doing please refer to a qualified service person only.
