I bought a stereo amplifier and a turntable, both old but still functioning. However, I have been encountering some problems.
Before I got the stereo amplifier, I was using my old Sony stereo component with phono input, and there were no problems at first. Then recently I noticed that the sound from the right channel was quite distorted, so I decided to get a new amplifier. It has a knob for stereo or mono. In stereo, there's normal and reverse, while in mono, there's left, right, and left + right. If I place it in stereo, there's no or very weak sound in the right channel. But in mono left + right, there's balanced sound in both channels. However, there's no sound when switched to mono right.
Then I checked the touched the headshell wires of my Hitachi Lo-D HT-462. At first, just touching the headshell produces a humming sound even though the turntable is properly grounded. And when I played a record, there was very little sound coming out from the speakers. I touched the wires again, and there's no more humming sound and the volume is back to normal, but still no sound in the right channel when switched to mono right.
Is this normal? If not, is it a turntable or amplifier problem? Thanks in advance.
