What seems to be trouble is not always real trouble.
Make sure first.
No sound at all 1. Are the cables connected properly?
(Cables should be connected firmly and properly.)
2. Is the amplifier tape monitor switch turned on?
(The tape monitor switch should be turned off.)
3. Is the amplifier source select switch set to the "TUNER"
or "AUX" position?
(The select switch should be set to "PHONO".)
4. Is the connection to the amplifier proper?
(Connect properly.)
5. Is the amplifier volume control set to "M IN"?
(The volume knob should be turned clockwise to the
desired level.)
6. Is the tonearm connector nut loose?
(The connector nut should be tightened firmly.)
7. Are cartridge wires disconnected or loosely connected?
(The cartridge wires should be firmly connected.)
Noise when playing record. ..
1. Is the record worn?
( Replace with anew one.)
2. Is the stylus tip worn?
( Replace with anew one.)
3. Is dust on the stylus tip?
(Clean with a stylus cleaner.)
4. Is the record dusty?
( Clean the record grooves with a record clea ner .)
5. Are the red and white plugs from the turntable properly
connected to the "PHONO" terminals of the amplifier?
(Connect th~m properly.)
6. Is the grounding cord (black) connected to the grounding
terminal of the aimplifier?
(Connect it properly.)
The platter does no turn. ..
1. Is the power cord connected to the AC outlet?
(Connect it firmly.)
Loud howling. ..
1. Is the turntable too near the speaker?
( Position at least 40 cm from the speaker .)
2. Is the turntable located on the speaker box?
( Move to a place as far from the speakers as possible.)
3. Is the volume or bass tone control emphasized to distort
the sound?
(Decrease the volume or bass tone control to a level
providing undistorted sound.)
