My name is Graham Bell and am in the Philippines. When I look at other correspondence I feel very ignorant. My problem is I have an ancient excellent NVA amplifier and need to buy a cartridge for equally ancient AE turntable. Do not know if ceramic or magnetic is compatible. No manual, long lost. No model number or any markings outside or in. Description, bought circa 1982. Black. Dimensions 40cm wide, 7.5 cm high, 21 cm deep. On/off toggle switch at back left upper corner. Volume control on front 17 cm from right. Aux/tape/tuner/disk next to it. Think it cost about £200. Very grateful for help. Am not able to buy new equipment.
