CAT Phono Stage

I'm having terrible problems with my phno stage, which picks up so much hum that it blows out the amp fuses. I'm running a Linn LP12 with Lingo power supply. I'm about to give up on the CAT phono stage and get a solid state Linto. Any suggestions on rescuing my phono stage?
Your problem should be curable, and I wouldn't give up on the CAT's great phono stage unless I really had to. Try calling Marty Reiss at CAT. Sorry, I no longer have his phone number, but if you have the manual, you will. He's been very friendly and helpful with me, and I'm sure he'll give you a few suggestions to try. Good luck!
I might be one of the few who had to disconnect the ground from the tt.You might try it w/ no volume. Also, is the hum in both channels? If it's only one channel;swap the right left ics. No other source has hum? Good luck.
Alas, the hum is in both channels, more on left than right, though. I think it's RF. I'm not sure there is a cure, but will call CAT. It would be a shame to abandon the phono stage.
