Hadn't used the turntable for a while, put a record on and was distracted by something elsewhere in house. Came back 10 mins later and could hear something not right. Listened properly and one of the channels was a bit quieter and had also lost much of the higher freq. Did a fair bit of diagnostics over the next day or 2 - swapping L&R phono leads into phono preamp, swapping phono preamp, swapping amp/speakers, disconnecting reconnecting cartidge tags, swapping cartridge tags round, removed and reseated stylus a few times. Not necessarily in that order of course! Anyway end result is that the problem is definitely with cartridge/stylus - its associated with the pins on the rhs as you look at the arm from the front - can't remember if thats the lh or rh channel as Ive swapped so much round! Cant swap the stylus as I only have the one. Only bought the cartridge in june/july so will likely return it, but wanted to see if anyone had any thoughts? I do have a multimeter so could measure if that would be useful?
