RedPlate RPHD100 Operations Guide
Your RPHD100 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). 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 use on front and rear panels.
All tube brands are acceptable, a long plate is preferred in the V3 (Phase Inverter) position.
