Turntable rumbling

Hello Friends, merry xmas
I have at the moment, a Michell Tecodeck turntable, with a Garrot Bros updated P77 cardridge, I have bought new speakers and amp, Redgum amp, with phono stage, and Usher speakers, I have enjoy the "Break in Stage" of all equipment, as It was so much better, but after approx 50 hours use, all of a sudden the LP,s, have a bass boom, at the start of the LP, and any warped LPs is un playable, I took out the styls, from the cartridge, and seems OK.
All My LP's are mimt no clics and pops!!
The last time I played the LP's was on a Well Tempered Classic, an I had no promblem.
I have set the cartridge, on the correct weight, well the Sure was 1gm out compare to the digital, friends I'm geting upset not good after a heart attack!!
Can someone put me on the right track, as I have just got back into Hi Fi, Where I live down here, on the South Coast of Australia, there is no shop, that deals with Hi-Fi, to get any assistance I have to drive 4 Hours to Sydmey!!
Kindest Regards
David Spry

Dear Davey,
Is anything interfering with your turntable mechanically i.e. anything different such as heavy speaker cables touching the stand(?) or touching the cable feeds to your phono stage or turntable?

Another possibility is temperature changes from when you first aligned the cart?
If it was done in colder conditions and the cart is now many degrees hotter, your VTA may have become noticeably upset? If you are using a Michell Technoarm then altering VTA may be problematic(??)

Also, Davey, try having a look and seeing if the underside of the cart is "bottoming" on the record as you cue it?
Just a thought...?
