Right channel makes raspy noise when playing records

Hi all
I have a Music Hall 5 TT with a Goldring cartridge. 6 months ago I replaced the stylus and it sounded great. yesterday I played brand new 180g vinyl  and there was a scratching sound from the right channel. It made this sound on every record and if touch the TT with the stylus sitting on the record, (not rotating) it still makes the sound.   I am pretty sure this is specific to the TT (tested the rest of the system and no problems. )  Do Cartriges degrade so suddenly ?

It is about 8 to 10 years old.

i did the reversal and indeed it is my phono preamp.  i have a tube preamp and believe the problem to be microphonic tubes as i have not replaced them in 9 years.

Check out Brent Jessee Tubes. I've bought some very nice NOS & used tubes from him. Service is great. 
Yeah 9 years is a good run .
Microphonic tube.  Yes.
