Thanks for all your replies chaps. I'm certain its a GL '88' turntable.
At somepoint I will dig iti out of my Dad's loft and see what condition
its in. Same for the EPU 100 arm but I'm not convinced stylii are
available for the cartridge anymore (it has a red pip mono and white
pip stereo cartridge). I have a much newer AR EB101 turntable available
to me so its just a question as to what my Dad and I do with his
antique pieces that have been in the family for 40+ years.
