Chapter Seven: Maintenance and Cleaning
7.1 Cleaning
Never use anything wet to clean the amplifier, any amplifier. Usually, it issufficient
to wipe down the outside of the amp with a slightly moist cleaning rag. Do not use
abrasive cleaning chemicals. Sometimes a vacuum cleaner can be usedto remove
dust and dirt from nooks and crevices. Do not remove the chassis from the housing
to clean the amp; the inside of your amp carries dangerous Voltages.
7.2 Care
Be gentle with this Amplifier. Any mechanical shocks, extreme
temperaturechanges, damp environments, and other extreme conditions (dust,
wind) cansubstantially shorten tube life. In some cases, even the amplifier life. Do
not block the air circulation grilles in the back of the amp. Do not push the amp
right up against objects that would interfere with its normal airflow. The top of the
amplifier might get warm after a prolonged use; this is normal, but will melt your
ice cream and definitely ruin your beer. Never put beverages on top of the amp
where they could spill and flow inside the amplifier. Will you rue the loss of your
beverage first or the loss of your amplifier?
7.3 Tube Change
Since Schmidt is a so called Cathode Biased Class A amplifier, you can change the
power tubes by yourself, no biasing necessary. Just make sure that you are using
only octal tubes (EL34, 5881, 6V6, 6L6, KT66, KT88, 6550), use matched pairs and
let the amp and his tubes cool down before swapping tubes.
7.4 Fuses
Your Schmidt has two external fuses – the mains fuse is located inside the mains
jack, which includes a small drawer. Pull it out (no chord attached to the amplifier)
gently. Inside it you will see two fuses, the one closer to the amp’s internals is the
active fuse, whicle the outer one is a spare.
