Classe CA-400 amp trips


I just bought a BAT 30SE Pre-amp(used)and I believe it's causing my Classe CA-400 amp to trip- green blinking lights comes on from the normal stationary red after playing the CD for half a hour or so.
I had been using a Krell RC-2 previously and never had any problem. Addtionally, I have a B&W N802's, Cary 306 CD player.
Any expert Audiogoner out there? Please help. Thanks.

Happy Holidays to everyone.

I had that problem with a CA200. After much searching I finally figured out it was the speaker cable, an MIT Oracle V3. Here's where it gets wacky, it happened only when I had a CJ premier 14 preamp in the system, PV10 no problem. Took the 14 to CJ, everything was fine, was not passing DC as I suspected. Now I use MIT M2 and the 14 with no problem. I also think Classe sets the bias very high which can cause tripping under some circumstances. Your preamp could be passing DC. Good luck.
John, you are absoluting right, such a nuisance as your experiencing is frustrating and shouldn't happen. Good luck.
