Front Panel

Note:

The 350 has been designed to provide many years of trouble free enjoyment. It’s important to keep the exterior of the unit clean and to periodically ensure that the air-cooling grills remain clear from obstruction.

Please switch the unit off and remove the cord-set from the rear of the amplifier before attempting to clean your 350 in the manner described below.

Never apply liquid directly to the 350.

Never use abrasives.

Never rub in a circular motion.

The cover features a durable, high quality powder-coat finish. To remove finger marks and dirt, lightly rub the surface with a soft cloth.

If the dirt is not removed, dip your cloth in a mild solution of soap and water, squeeze excess moisture from it and then gently reapply to the surface.

Stubborn dirt may be removed by the application of a small quantity of methylated spirits, applied directly to the cleaning cloth only and reworking the effected area.

The 350 front panel features a high quality electroplate finish. Over time the surface may retain finger marks and may need to be cleaned to restore it to original condition.

Regular Cleaning

Gently wipe the front panel with a very clean cotton cloth. Wipe across the surface and never in a circular motion.

Removing Stubborn Marks

Only attempt this infrequently, as too regular or vigorous application may damage the surface.

Apply a small quantity of any car polish containing carnauba wax to a very clean cotton cloth.

The car polish must state “Safe for Clear Coats” as the polish will therefore contain the absolute minimum amount of abrasive compound.

Gently wipe over the front panel in lateral motion, allow to dry and then gently wipe off with a very clean cotton cloth.
