Re: AVO 163 amp board ~ transformers
Specs for Oscillator transformer:
----------------------------------------
Oscillator Transformer:
PRIMARY:
Resistance: 85 Ohm +/-10% at 20°C
SECONDARY:
Resistance: 27 Ohm +/-10% at 20°C
Voltage test: Apply 1 Volt RMS at 15 kc/s from a suitable oscillator to the primary winding. Measure open circuit secondary voltage. This should be 0.5 Volt RMS +/-5%. Use a Hewlett Packard VTVM model 400H to measure these voltages.
