not practical to switch to 90 V in a 60 VAC system. There is no damage to the amplifier if the selector is not changed from the standard 60 V setting. However, changing the selector ensures that the DC supply does not turn on until the proper input voltage, 38 VAC or 55 VAC, is reached. This prevents excessive loading of the system power supply during turn-on after a system shutdown.

The power supply also includes the fast-transfer electronic-crowbar (FTEC/BTA) surge protector, except for the basic models (BT*-100*H) which include a gas discharge tube. The FTEC/BTA fires at approximately 245 V and presents a short circuit to the line during periods of over voltage. After the AC input voltage returns to normal, the FTEC/BTA resumes its open state. Although the power supply is located under the electronics chassis, you can access the gas discharge tube or FTEC/BTA through the cover on the top side of the electronics chassis.

Figure 2-8 illustrates the location of the 60/90VAC voltage selector on the power supply circuit board.
