2. INSTALLATION

2-1. Unpacking and Initial Inspection

Before you start any action on installing the amplifier, thoroughly read through this
manual. First carefully inspect both cardboard cartons and their contents for physical
damage. If damage is noticed, notify your dealer immediately. Delay may infringe
carrier's warranty conditions. Keep all packing for possible future transportation!
In order to take the RCU out of the amplifier, remove the cover by removing all screws except the eight
located in the tube exhaust areas. Remove the plastic tubes holders but keep them for possible
future transportation.
Check the HV Crowbar (Fig. 2-1) - it must reliably shorten the HV lead to
the chassis when cover is open.
Take the RCU out and free the compartment for installing the transformer. Carefully inspect the RCU
and the amplifier main components for any possible shipping damage.
Check carefully the serial numbers of amplifier and tubes with the Table of Individual
Data (Table 2-1). If you find any discrepancies notify your dealer immediately to
have your warranty information corrected.

2-2. Line Voltage Selection

To avoid damage (not covered under warranty), check carefully if the voltage for
which the amplifier is set corresponds to your mains nominal voltage. Most 120V
and especially 100V domestic mains installations may not withstand the current
consumption and you will have to reduce the output power to about 1000W PEP .
