    1.1.2. LEAKAGE CURRENT HOT CHECK (See Figure 1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check. 2. Connect a 1.5k , 10 watts resistor, in parallel with a 0.15 capacitors, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 3.

  • Page 8: Protection Circuitry

    Current consumption at AC 220V-230 V, 220V/230V-240V, 50Hz in NO SIGNAL mode volume minimal should be ~ 600 mA (For EB). 1.3. Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: - No sound is heard when the power is turned on. - Sound stops during a performance.
