Powering Up - Mapletree Super Stealth + User Manual

Powering Up_______

Please read this instruction manual thoroughly before powering up your Super Stealth +
amplifiers for the first time. The location of the tubes is shown below. When installing
tubes, locate the key on the central spigot and make sure it matches with the indent on the
tube socket. Push the tube into the socket with a slight rocking motion to ensure it seats
properly. Removal is also easier of the tube is rocked slightly as it is pulled out. Don't
over-do the rocking as it can cause the spigot to break off. The EL34 output tubes are
installed as matched pairs as indicated on the boxes supplied with your amplifier.
Matched quads are not required for two monoblocs.
With the tubes installed, connect the IEC power cord to the AC input receptacle on the
rear of the chassis. A proper sized fuse (3 A/250 V fast blow type) has been installed in
the ac socket drawer. Plug the cord into an ac outlet rated for at least 200 W (110-125
VAC, 50-60 Hz). The ac power switch is on the front panel. The pilot light indicates the
AC power is on. You will see the heaters light up, particularly in the EL34 tubes. It takes
approximately 60 sec for the plate voltage to settle to the operational level and stabilize.
