Hi a friend has inherited a Beomaster system, amp, cassette deck, turntable. The turntable is not working, the arm skids off the record straight away. Hooked up another turntable, but I think it was overdriving the phono circuit a bit, although there was something tantalising about the sound quality..any thoughts on a suitable turntable and any particular spec required for speakers? Would love to get this thing going again..
