Move the transformer, using its rope sling handle, into the compartment. Take care not to
damage the wiring or components and position the transformer so that the captive nuts are
aligned with the corresponding chassis holes. Make sure that the transformer is centered. The
transformer bolts must be installed NOW for safe operation.
Holding its two sides (front and back) simultaneously, pull the amplier towards you just far
enough that the two outside transformer captive nuts appear off the table edge. Support the
amplier until your assistant loosely screws in the two outside transformer-mounting bolts. Pull
the amplier a further 12-13cm (about 5 inches) until the other two captive nuts appear off
the table edge. Keep supporting the amplier until your assistant loosely screws them in. After
checking that the transformer is centered, tighten all 4 bolts. Now move the amplier back over
the table.
The transformer's Mains Connector plugs into the AC power console (Fig.2-1). The other three
connectors (HV, Motors Voltage & Screen Grid Voltage) plug into the HIGH VOLTAGE PCB,
clearly seen on top.
Replace the cover and carefully reinstall all screws.
2-4. Connections
The amplier is now ready to be connected to your station. Connection must be accomplished
in the order described below, before you apply mains voltage to the amplier.

Have in mind that the grounding system may have to withstand currents
over 20A with insignicant voltage drop on it. Therefore it may be
necessary to improve it considerably (to become lower-resistive, i.e.
with heavier leads and lower-resistive ground path). The grounding leads
should be at least 8mm
