VA300-S Speaker Servicing:
1. Unplug cables from speaker jacks.
2. Remove back of cabinet.
3. Disconnect one end of the lead connected between the
two 10 inch loudspeakers.
4. Apply 60 Hz, 1 to 10 volts, to each of the six speakers
individually. Any buzzes or rattles indicate possible
failure. The speakers should all sound generally alike
with a slight difference between the 8 inch and 10 inch
loudspeakers.
5. Using an ohmmeter, measure resistance of the voice-coil
of each loudspeaker individually. Each 10 inch speaker
should measure between 12 and 16 ohms. Each 8 inch
speaker should measure between 5 and 8 ohms. Read-
ings outside of these limits indicate possible failure.
6. Reconnect lead disconnected in Step 3. Install back of
cabinet tightly.
