Hum from speakers -
Usually a grounding issue. Flip the ground switches. Start with
off.
Drifting center image –
Usually caused by a 12AU7 signal tube. When they go bad, it
will slowly fade away. You can tell when your center image drifts to the left or right. We
recommend you replace every 2 years.
LED lights –
The front LED Amber light is the low voltage indicator, and the green LED
light is the high voltage indicator. If both lights go out, check the mains fuse. If only one light
goes out, you will need to call the factory.
Cleaning
Dust your tubes and unit with a feather duster.
Don’t use any liquid cleaners like glass cleaners on your tubes, just dust them.
Gold plated tube sockets and connectors are “self-cleaning”. Do not use any liquid
aftermarket tube socket or connector cleaners.
The black powder coat finish can be cleaned with glass cleaner or alcohol. Sprayed
onto a micro-cloth. Never spray any liquids directly onto the unit.
Use a stainless steel cleaner sprayed onto a micro-cloth on the mirrored stainless steel
curve. Use a separate super soft microfiber cloth and gently remove the residue.
