Troubleshooting
Some tips:
• No output. Power is on, but power LED is off and tubes do not light up.
Mains fuse is out. Replace fuse as per instructions on page 12.
• No output. Power LED is on and tubes do light up normally.
The CD player stays muted for 30 seconds when powered on. Check to make sure all
interconnects are securely connected. If all seems to be OK check other equipment in use.
• Remote control does not respond.
Batteries are low and have to be replaced. Strong (sun)light may also disturb the remote control
signal. Make sure there are obstacles between remote control and CD player.
• Noise coming from one channel.
Noisy tube. First swap the 12AX7 tubes left to right. If noise follows tube swap, than you have
found the problem tube. If noise does not follow, swap the 12AU7 tubes left to right. If noise still
persists, contact your dealer.
• Hum coming from one channel.
Check 5AR4 tubes to make sure they are seated properly. Swap L to R , if hum follows tube then
replace faulty tube.
• Noise/distortion coming from both channels.
Tubes may be in need of replacement. Read page 11 for tube basics and replacement options.
Please also check the other equipment in use for failure or improper connections.
If you try these possible solutions and problems persist, contact your local distributor for further
investigation.
Tube Selection
While matched tubes are not a requirement, they’re still recommended if you want to get superior
results. You can get the very best in replacement tubes as well as rare vintage NOS (New Old Stock)
from us and other parties if you wish to upgrade. In the USA, Upscale Audio’s inventory of New Old
Stock tubes is the largest you can find. Elsewhere, independent suppliers can assist you in making the
best choice
