WARNING
Maintenance and repair of the KV5-100 mk3 series must only be carried out
by suitably qualified and trained personnel. Potentially lethal voltages are
present inside the unit and on the output leads.
Ensure that the unit is disconnected from the mains before removing
any covers.
It is advisable to check the carbon brush on the variable transformer for signs of wear on a
regular basis. To gain access to the variable transformer remove the top cover of the unit
(secured by four screws - two in each side of the case).
Replacement brushes are available from T&R Test Equipment.
