TUBE 50/100 - MANUAL
MAINS FUSE: AC power fuse. Ensure you use specified replacement fuses only, as needed depending on the local voltage.
MAINS IN: Connect the included
POWER TUBE STATUS LEDs: If one of these LEDs illuminates continually, then the corresponding power tube is defective (cathode short). Even if the TUBE 50 / TUBE 100 continues to operate (with reduced power and an altered sound), the tube and the corresponding fuse must be replaced as soon as possible to avoid damaging the amp. Note that the POWER TUBE STATUS LEDs indicate a cathode short only, and no other power tube defect.
Don't be alarmed if all POWER TUBE STATUS LEDs illuminate at once briefly in response to your picking attack (at higher volumes). This indica- tes the tubes are operating correctly. If one of the LEDs does not illuminate along with the others, this may indicate a defective tube heater or a faulty contact at the tube socket.
MIDI MODULE PORT: When a qualified service technician installs the MIDI Module in your TUBE 50 / TUBE 100, he must remove this cover plate first (after removing the AC power cord and waiting at least 2 minutes for the amp to power down).
