Antique Apparatus /Rock-Ola Gazelle cd8 static
Posted: Sun Apr 06, 2014 6:28 pm
After 3 years of blindly flailing away at this box (with some crucial help from this board), I finally got it to work!
Now that it actually plays I find it has a bit of unwanted noise coming out of the speakers. When the CD player (a 1994 model CDM-4 industrial ) is playing a CD the speakers sound like a wind-burned recording with a rustling sound, randomly accompanied by pops and flat-out static. This noise doesn't increase when you turn up the volume so I can overwhelm it with music, but that usually isn't an ideal situation in a house full of people who don't like hearing the Pouges Greatest Hits on heavy rotation!
I changed the Volume control potentiometre but that didn't have any effect, all the connections seem tight and everything is mutually grounded. I also cleaned the laser on the player and have tried wiggling and tapping everything I could reach, yet dispite all this abuse the noise neither varied nor stopped.
Could a worn out CD player cause this or maybe a woggy amp?
Also, does anyone have the correct schematic of the display and keypad for this box? it is an early 1994 model which has the keypad/buttons below the title strip pages (which are manually flipped with a thumb-wheel) and the digital display is up top behind the glass arch. The manual I have from Victory Glass (AMR# R-574) only shows the later model when the buttons were combined with the display up top and the former keypad/button space got a blank-off plate that said "Rock-Ola".
I once again thank you all in advance for your help,
Dale
