Servicing and configuration
FSL offer a comprehensive service for the SAM-A1 amplifier and we are happy to provide you a
quote for work on your amplifier. Services offered include:
Mains Input set up – matching the SAM-A1 to your domestic mains supply is important. Too
low a supply setting and the amplifier may produce hum at the output; too high and the unit
will waste energy, get warmer than it should and run the valves heaters hotter, reducing the
life of your valves. If you do not know what your mains supply voltage is – a qualified
electrician will be able to test it for you if your provider is unable to tell you what it is. Active
sockets are also available to tell you how much power/energy an appliance is consuming and
they often have a voltage readout (we can recommend a device for you but are unable to loan
them out for liability insurance reasons). If you measure your mains supply with one of these
active sockets, write down the voltage reading at different times of day for a few days and
then send us the active socket and your readings, we will then check the reading on your
smart socket and select the most appropriate mains input setting for your amplifier before
delivery.
Failing that FSL can survey your mains supply for you during a visit to your installation and we
will configure your SAM-A1 to your mains supply. This is only offered to UK mainland and may
be subject to travel charges incurred.
6 month or annual re-biasing
Annual service including valve check, complete set-up and re-calibration of the amplifier.
Amplifier valve exchange – change the valves for a new set of the same type or a different
grade – including a complete set-up and re-calibration of the amplifier.
Amplifier valve roll - change either the input and driver or the output stage or all valves for a
new set of a different type of valve - including a complete set-up and re-calibration of the
amplifier.
Amplifier re-configuration, e.g.
Change output stage: e.g. from small triode to large triode, from large triode to
pentode or pentode as triode
Change input stage, e.g. from paraphrase inverter to cathodyne
This includes a complete set-up and re-calibration of your amplifier.
Amplifier repair – in the very unlikely case that the amplifier develops a fault out of warranty or
is damaged; we will assess your amplifier and quote to repair it, either to a functioning but as
received condition or back to the as-bought condition.
