Troubleshooting; Technical Specification - Hughes & Kettner Edition Tube 25th Anniversary Mode D'emploi

B e sure the AC power source delivers the current
that your amp is designed to handle before you
plug it in. When in doubt about the local rating,
ask the venue's sound t echnician or a stage hand.
R efrain from DIY repairs! To be on the safe side,
you should also have a qualified technician replace
internal fuses.

5.0 Troubleshooting

The Edition Tube is not getting any power:
• C heck the mains cable to see if it is connected
properly.
• T he mains fuse may be defective. Replace the fuse
with another identical fuse. If this fuse also trips,
consult your Hughes & Kettner dealer.
The Edition Tube is connected properly, but no
sound is audible:
• O ne or several GAIN and MASTER controls
may be turned all the way down. Dial in a higher
setting.
• A short circuit in the speaker signal chain may have
t ripped an internal fuse, or one of the power tubes
is defective. Replace the speaker cable and have a
q ualified service technician replace the fuse/tube
( identical specifications are a must). Please read
Section 4.0 on how to replace tubes correctly.
The sound is slightly distorted and you cannot get
a truly clean tone:
• T he input section is being overdriven. Depending
on the type of pickups in your guitar, this effect
is very p ronounced or may not be audible at all.
If you don't want this slight distortion (although
many players prefer a little dirt in their sound),
reduce the volume of your guitar or volume pedal,
turn the screws on the frame of your pickups so the
distance between the strings and pickups is greater,
or try a different combination of pickups.
• I f the distortion has an annoying gritty edge to it,
there may be some type of fault due to improper
use of a signal circuit, for instance a speaker output
connected to the Edition Tube's input. In this case,
consult your Hughes & Kettner dealer.
You have connected an FX processor to the SEND
jack and the signal is totally distorted, even when
you have dialed in a clean sound:
• T he LINE OUT signal is overloading the input
of the FX p rocessor. Reduce the processor's input
sensitivity ("INPUT" or "GAIN").
You have connected an FX processor to the SEND
jack of the Edition Tube and the signal's volume
level is way too low:
• T he FX processor's output level is set incorrectly.
Turn it up.
