Marshall 1987X reissue is noisy as heck when you turn it on

[Bluesbubba]

My Marshall 1987X is an awesome amp right out of the box but it's quite noisy. Some Les Paul brothers recommended that I get NOS RCA or Mullard preamp(12ax7) tubes and take out the marshalls and Clay Finley suggested that I change the coax and a 68k resistor(i think that's right).

Anyways any thing or direction would be greatly appreciated. I live out in California so any Amp gurus that you would suggest, however I am pretty handy to do things myself!

Sincerely
Bluesbubba
