1.1. GENERAL GUIDELINES 1. For continued safety, no modification of any circuit should be attempted. 2. Disconnect AC Plug before disassembling this unit. 3. It is advisable to use an isolation transformer in the AC supply before servicing. 4. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.
Page 5 3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet and repeat each of the above measurements.
